Question

arrange in order of increasing atomic radii.
(a) Si,P,C,N.
(b) Si,P,Cl,Br
(c) O^2- , N^3- , S^2- , F^-
Plzzz tell fast​

Answer 1

Answer: a)N<C<P<Si

              b) Cl<P<Si<Br

              c) N^3->S^2->O^2->F^-

Explanation:Arrange the elements the sequence of increasing atomic no. and then find the ans by keeping in mind the concept that  in elements falling in the same period  the one with lower atomic no. is larger in size

this is the explanation for first two questions

3) the more the electrons an atom has to gain to achieve noble gas configuration the larger will be the charge and the longer will be the radius since radius increases is the atom is negatively charged
