Question

With refrence to the elements of group 17 of the periodic table,the atomic size of the elements increases in the order
a) F<CI<BR←l
(b) I<Br<CI<F←l
(e) F<Br<CK←l
(d) Br<F<CK←l​

Answer 1

Answer:

Atomic radius increases down Group 17 from top to bottom. Electronegativity decreases down group 17 from top to bottom. Chemical reactivity of group 17 elements decreases down group 17 from top to bottom. First ionization energy decreases down group 17 from top to bottom.
