As we move from right to left in a period , nuclear charge increases by 1 unit , but the number or shells remain same (in periods) , due to this increased nuclear charge , the electrons are pulled back to the nucleus making the shell smaller...

so acc to me

it shud be

C > N > O > F

but Neon will have the highest radius coz in noble gases , orbitals are completely filled so electronic repulsions are max. in them , also noble gases have van der waal's radius.....and all other elements have covalent radius.....and we knw that van der waal's radius is greater than covalent radius

so order will be

Ne > C > N > O > F

I always like to walk in rain as no one can see me crying there :( frnds are like diamonds , if u hit them , they don't break but they slip frm ur hands -----It is better to be hated for what you are than to be loved for what you are not.---- *****wen love and skill work together--expect a masterpiece*****
