Question

atomic radius goes on decreasing while going from left to right in a period​

Answer 1

Explanation:

when we move from left or right in a period atomic size goes on decreasing and atomic number by one.The positive charge on nucleus increases by 1 unit also the electrons are added to the same shell by 1.Due to the increase nuclear charge the electron circle towards nucleus to greater extent. Thus atomic radius decreases and finally atomic size decreases.
