Question

How does atomic size vary from left to right in a period?

Answer 1

Answer:

Atomic size decreases across a Period from left to right as we face the Table, but INCREASES down a Group, a column of the Periodic Table. ... And thus across the Period nucular charge predominates, and draws the valence electrons towards the nuclear core, with the result of a marked decrease in atomic radius
