There are seven periods in modern periodic table. As we move from left to right in a period valecy increases from 1 to 4 and then decreases to 0. When we move from left to right in a period metallic character of elements decreases and non- metallic character started to increase. As we go down in a group valecy of element remain same and atomic size start increase

The modern periodic table has seven periods.

On moving from left to right in the periodic table, the metallic character of elements decreases, while the valency first increases from 1 to 4 and then decreases to 0 (zero). On moving down the group, the atomic size of the elements increases, but the valency remains the same.
