How The Periodic Table Works-

Its based on the structure of atoms, the arrangement of electrons.
As the number of protons, or atomic number, increases the numbers of electrons also increase.
Periods end when valence electrons reach 8.Group 1's elements have 1 valence electron.Group 2's elements have 2 valence electrons.Group 7's elements have 7 valence electrons.Group 18 's elements are made up of noble gases. Atoms, except for helium have 8 valence.When atoms have 8 electrons it is stable.
A period is a row in the periodic table. It is arranged in order from lowest to highest atomic number. Periods are numbered from 1-8 from the top row to the bottom. Below the main table there are two long rows of 14 elements. Z=57 is known as lanthanides. The other group below it is called antinides.The verticle colums are called groups.

Organizing The Elements-

Each element is represented by a symbol, usually an element is represented by one or two letters.On the periodic table the elements are organized into groups such as metals, nonmetals, gases, liquids, solids, and metalloids.These elements are then organized across the periodic table by something called an atomic number.The atommic number is the amount of protons that are in the nucleus of an atom.The elements are then organized on the periodic table by the incresing of the atomic number.


Reactive Non Metals And Metals-

The sodium is an alkali Metal which reacts vigerously with Bromine. Also Halogens react with these two chemicals to. Group 17 of the periodic table are called the halogens. Group 1 of the periodic table is called alkali metal. Also steel wood burns when it is exposed to halogen chlorine. When iodine a halogen reacts with aluminum a purple gas is produced. The atoms are more stable by losing their one valence electron. Thats why its good for them to lose there valence electrons so fast.Thats why the alkali metals are highly reactive with the halogens.external image periodic.gifThe Elements mostly involved with the periodic table group 18. The gases liquids and solids also go with the halogens and the alkili metals to.
