Question

14 aasesertion;atomic radius decreases in moving from left to right in periodic table
Reason;as we move from left to right the nuclear charge increases which tends to pull the electrons
closer to the nucleus​

Answer 1

Answer:

In a period from left to right the number of valence electrons in the same shell increases due to which the effective nuclear charge increases and therefore atomic size decreases as we move from left to right in a period.
