Question

WHY ATOMIC RADIUS DECREASES AS WE GO FROM LEFT TO RIGHT WITHIN A PERIOD .PLZZ GIVE DETAIL EXPLANATION IN SIMPLE WORDS .​

Answer 1

Explanation:

Atomic radius decreases as we move left to right in a period because the number of consecutive electrons get added in the same shell and hence the atomic radius of the elements across the period becomes constant . Thus, wrt to atomic radius along the group , the atomic radius of the elements across the period seems to be decreasing.

Answer 2

Answer:This answer is have easy language word... So i hope u will understand...!!

Atomic radius decreases from left to right within a period. This is caused by the increase in the number of protons and electrons across a period. One proton has a greater effect than one electron; thus, electrons are pulled towards the nucleus, resulting in a smaller radius.

Hope you understand!! Bro!!
