Answer 2

Answer:

See in the explanation.

Explanation:

GROUPS

Groups are the vertical row which is present in the periodic table

The periodic table contains 18 groups in total.

Down the group the atomic size of the atoms increases and as a result the non-metallic character increases.

The elements belonging to the same group have similar chemical and physical properties.

PERIODS:

Periods are the horizontal column of the periodic table.

In the periodic table, there are 7 periods in total.

Along the period the number of shells occupied by the electrons remains the same.

the properties of elements change from one another along the period.
