Answer 2

Generally as we go from left to right side of the periodic table the atomic radius decreases and the atomic mass increases.

This is because due to increase of charge in the nucleus force of attraction on outermost shell increases resulting in decreased radius.

As atomic number increases atomic mass increases.
