Answer 1

Atomic radii of elements increasing on moving down the group in a periodic table due to successive addition of shells. On moving left to right in a periodic table atomic size decreases due to increase in nuclear charge. Cations always have smaller size than it's respective atoms & anions have always larger size than their respective atoms. According to the position in periodic table, these elements can be arranged on the basis of atomic radii. Li > N Br < Br^- Ca > Ca^2 + Ar > Ne 0 < s Na^+ > Mg^2 + N^3- > O^2- Al^3 + < P^3-
