Question

In general, the atomic radius of an atom _______ as you move to the right across the periodic table? increases decreases increases then decreases remains constant

Answer 1

decreases as you move to the right

Step-by-step explanation:

Answer 2

Answer: decreases

Step-by-step explanation:

Atomic radius in a period from left to right decreases due to increase in nuclear charge.

On moving from left to right, electrons are getting added in outer shell and no of protons also increased which results increase in nuclear charge. Increased nulcear charge holds the electrons tigthly hence electrons moves close to nucleus. So radius decreases.
