Question

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

Answer 1

Due to effective nuclear charge ,as it increases when we move from left to rightdue to addition of more electrons in the outer valence shell. As a consequence theatomic radii decreases. Originally Answered: Why does atomic radius decrease from left to right in a period? Theatomic radius decreases from left to right.

Answer 2

Answer:

Explanation:

As we go from left to right,one electron is added in same Valence shell,as a result of which, effective nuclear charge increases, which leads to decrease in atomic radius, hope you understood.
