COMPARE THE ELEMENTS

       COMPARISON AND CONTRAST

       When we compare or contrast items, we make statements of similarity or difference. These statements, as with statements of classification, may be based on the way things function, the way they look, their use, where they are found, etc. It is important to remember that when you compare and contrast, you make parallel statements; that is, you make similar statements about the items under discussion. You compare colours with colours, size with size, the policies of one government leader with the policies of another. You don't compare sizes with colours, or locations with use, or policies with personal beliefs.

PERIOD

 Periodic Tables [of] element consist of chemical elements which have been found or made; they [is] arranged, in atomic number sequence in seven horizontal period, with lantanoid ( lantanum, 57 till lutetium, 71) and actinoids ( aktinium, 89 till lawrensium, 103 

FACTION

 Six august gas ( helium, neon, argon, krypton, xenon, and radon) emerge [at] tip of from is sixth [of] period of Grup 18 ( 0) periodic system group. This [is] reference appliance in tables for horizontal network [of] element as vertical series and period as a group. Seven element of lithium till fluor and seven appropriate element of natrium till klor placed.

Difference of[is Nature of Physics and Nature of Chemistry :

Nature of physics and nature of kima represent the included in the nature of items. Following is its difference 

•  Nature Of Physics

        Nature of PHYSICS is the nature of had by the items moment items do not turn into new items. Example of from nature of physics : emited a stream of by Easy of electrics current and have high flexing 

•  Nature Of Chemistry

        Nature of Chemistry is the nature of items related to formed its of new items. Example of from nature of kmia : Easy rust and easy to decay.

         Our periodic element comparison matrix allows you to compare up to 4 periodic elements side-by-side. Compare any of the 118 elements, such as Gold, Aluminum, or Titanium. Compare detailed attributes that includes electron configurations, melting points, and much more!

ELEMENT 

1.  Subdividing of element pursuant to metal and non metal 

       Concept: Element is single Iihat vitamin which cannot be elaborated again become other Iihat vitamin with reaction of ordinary chemistry 

 Items lapped over from some compiler particle. All man of science classify Iihat vitamin or items become two group, that is: single Iihat vitamin and mixture. Element and compound of is included in single Iihat vitamin faction. So, what such with element? Element consist of metal and non metal.

       Pure  vitamin measure up to differentiating with other Iihat vitamin. For example, hydrogen element only lapped over from just hydrogen atoms. Oxygen element only lapped over from just oxygen atoms. Nature of hydrogen and oxygen do not see at formed of vitamin both, for example water ( H2O). [In] nature there are 92 natural element type, while rest is element made in. Element grand total in nature about 106 element type.

         Element grouped to become three ( 3) shares, that is 

1. Metal element ( metal element ).

        In general metal element measure up to lustrous white chromatic, having low absolut zero, can send electrics current, can be forged and can send heat or kalor. In general metal represent solid Iihat vitamin, but there are one extant metal element melt that is mercury. Some worthwhile metal element in life of sehari–hari, for example a. Khrom ( Cr) Used for the bumper of car, and mixture with steel become steel stainless b. Iron ( Fe) Represent cheapest metal, as mixture with carbon yield steel for the construction of building, and car of rel train c. Nickel ( Ni ) Solid Nickel very hold up to water and air at ordinary temperature, therefore nickel used as by resist by gilded d. Copper ( Cu) Copper used many at power cable, ornament, and metal money. Copper mixture with tin yield bronze while copper mixture with zinc yield brass e. Zinc ( Zn) Zinc can be used as by house roof, tool of household, and pelapis of iron to prevent rust f. Platinum ( Pt) Platinum used by at car knalpot, electrics contact, and in the field of doctor as peacemaker of bone which broken g. Gold ( Au) Gold represent metal very [do] not reaktif, and found in the form of purification. Gold used as [by] high electrics component and ornament with quality. Gold mixture with silver used as by many coin materials.

 2. Element of is non metal 

        In general element of is non metal measure up to is not lustrous, ugly conductor, and cannot be forged. In general the non metal represent ugly hot conductor, but there are one element of[is non metal able to send heat better that is graphite. Some element of[is non worthwhile metal in life of sehari–hari, for example 

a. Fluor ( F) Compound of fluorid mixed with is functioning tooth paste strengthen tooth, freon – 12       as cooler of and kulkas of AC

b. Bromic ( used as by bromic Br) Compound of nerve tranquilizer, photography film, and fire             company Iihat vitamin mixture material.

c. Iodine ( I) Compound iodine used as by hurt antiseptic, additional of iodine in cooking salt, and       upon which amilum tes ( karbohidrat) in flour industry 3. Semi element of metal ( Metalloid).

Jons Jacob Berzelius ( 1779 ~ 1848), introducing procedures writing of element device and name, that is 1. Each;Every element symbolised with one taken away from [by] letter is letter early name of element 2. Element device written with letter of kapital 3. For element owning letter early is [is] same, hence writing of name differentiated by adding one letter rear and written with lower case 

 Example of: Element Carbon written by C, oxygen written by O, Aluminium written by Al, Calcium written by Ca.

Jons Jacob Berzelius ( 1779 ~ 1848), introducing procedures writing of element device and name, that is

 a. Each;Every element symbolised with one taken away from by letter is letter early name of element

 b. Element device written with letter of kapital

 c. For element owning letter early isis same, hence writing of name differentiated by adding one letter rear and written with lower case 

 Example of: Element Carbon written by C, oxygen written by O, Aluminium written by Al, Calcium written by Ca. 

 3. Semi element [of] metal ( Metalloid)

 Semi Element of metal measure up to between metal and non metal. Some semi element of  worth while metal in life of sehari–hari, for example a. Silicon ( Si) There are in nature many both or second after oxygen, namely 28 % from crust. Silicon compound used many in equipments of sandpapering and cutter, to be is semi of conductor, and also materials to make glass and is ceramic b. Germanium ( Ge ) Existence of germanium in slimmest nature, obtained from stone smolder and condensed zinc rock. Germanium represent materials of semikonduktor, that is at low temperature function as isolator while at high temperature as conductor 

 so called Chemical expert of Demitri Mendleev ( 1834 ~ 1907) raising periodic system tabulating
of elements. How element device and name written down? To the number of element which there are in nature enough complicate us to keep in mind the name of element. Therefore, needed by an procedures to facilitate we remember the name of element

2. Law of Triade Dobereiner 

If elements in one the triade in order of increase of its atoms mass, especially atomic mass and also nature of second element represent mean of third and first element atomic mass. This invention show the existence of relation between atomic mass with nature of element.

 Weakness of this subdividing lay in fact that amount of element owning looking like of is nature of do not only 3

Tables Of List of Triade Doberreiner :

3. Law Octave of Newlands

       The Kecendrungan expressed as Octave law of Nweland, that is : if element compiled pursuant to increase of atomic mass hence nature of the element will be recuring after eight element 

     Tables of subdividing of element in Octave of Newlands 

 Octave list of Newlands compiled 

        August gas elements not yet been found in the reality this subdividing only according to for light elements ( Low Ar 

4. Law of Mendeleyev 

Year 1869. Nation Russia master of Dmitri Ivanovich Mendeleyev pursuant to perception to 63           element which have been recognized by that moment, please conclude that the nature of periodic     function element of atomic mass relative itshis. That thing mean if elements in order of atomic         mass kanaikan relative, nature of certain will be recuring periodical 

     

Mendeleyev also make a[n periodic list of element. Elements having equation of is nature of   placed in one vertical column is so-called faction. In grouping element – element having equation of[is nature of placed in one vertical column is so-called faction

In elements mengelompokan, medeleyev more menekakankan at equation of is nature of element compared to increase of atomic mass relative, so that there are empty tempat-temat in periodic tables.This vacant lots which is later;then forecasted will fill by elements which is was not yet found. Later;Then day of[is forecast of that proven by elements menenukan having the nature of which loo like according to its its his.

      

         Weakness Of Periodic Tables of the following Mendeleyev.

 1.Penempatan element disagree with increase of atomic mass relative because maintaining looking         like of[is nature of element in its one faction.

 2.Masih many unheard-of element at that mass so that in tables of there are a lot of vacant lot 

    Periodic Tables of Mendeleyev 

     

5. Periodic Tables [of] Modren

     Year 1914, Henry G. J. Moseley find that element in periodic tables according to increase of atomic number. Periodic tables of modren of[is so-called also periodic tables of long form, in order of increase of atomic number and looking like of[is nature of. Periodic tables of this modren can be told as completion of Tables of Perodik Mendeleyev
      Periodic Tables of long form consist of vertical column ( golongan) which in order of looking like of is nature of and column of horizontal ( compiled periode) pursuant to increase of its atomic number.
