What Is periodic Table It is a table of the chemical elements arranged in order of atomic number, usually in rows, so that elements with similar atomic structure (and hence similar chemical properties) appear in vertical columns.

Who Created 1st periodic table ?

Dmitri Ivanovich Mendeleev was a Russian chemist and inventor. He formulated the Periodic Law, created his own version of the periodic table of elements

How elements are arranged ?Elements are arranged in a increasing order of there atomic number.

Elements are arranged in Groups and Periods.

On the left hand side there are METALS

On the right hand side there are NON-METALS

GroupsElements are arranged in Groups and Periods.

Groups are seen as (12) vertical columns

Groups of number is equal to valance shell electron.

Member of one group have same number of valence shell electron and similar chemical property.

PeriodsElements are arranged in Groups and Periods.

Periods are seen as (8) horizontal rows.

Period is equal to number of shells.

Member of one period have same number of shell.

Metals In periodic table metals are arranged on

the left hand side.Examples :Group 1 is Alkali Metals.(lithium family)Group 2 is Alkaline earth

metals(Beryllium family)Key Points :These are transition metals These are also rare metals.

Non metals
