Question

Atomic radius gose on decreasing while going from left to right in a period write scientific reasons

Answer 1

Answer:

atomic radius goes on decreasing while going from left to right in a Periodic Table because for 1 unit rise in the atomic number ( one proton and an electron increases) the Z effective or the effective nuclear charge on the last electron increases. So,in layman language the nucleus keeps on becoming more powerful and now it is able to pull all the electrons toward itself, thereby decreasing the size of the atom and hence the atomic radius..
