Briefly explain the account explain the account of groups and periods in long from of periodic table .

Explanation

Groups: Vertical columns from 1 to 18 groups
Groups : 1 `rarr` Alkali net as
Groups : 2 `rarr` Alkaline earth metals
Groups :3 to 12 `rarr` Transition elements (d - block elements)
Groups : 13 `rarr` Boron family, Groups : 14 `rarr` Carbon family
Groups : 15 `rarr` Nitrogen family , family , Groups : 16 `rarr` Oxygen family
Groups : 17 `rarr` Halogens , Group : 18 `rarr` Noble gass.
Periods : Horizontal rows from 1 to 7 are peruses first period (IS) very short period, H and He is preset
Seconds period (2s,2p) `rarr` Short period, Li to Ne is present.
Third period (3s,3p) `rarr` short period , Na to Ar is present.
Fourth period(4s,3d,4p) `rarr` Long period , K to Krr is present.
Fifth period (5s,4f,5d,6p) `rarr` Long period Rb to Xe present.
Sixth period (6s, 4f,5d,4p) `rarr` Very Long period , Lanthanides are present
Seventh period (7s,5f,6d) `rarr` Actinides are present .
Here both sixth and seventh period are called inner transition elements.
