Question

5.
Elements X, Y and Z have atomic numbers 19,37 and
55 respectively. Which of the following statements is
true about them?
(a) Their ionization potential would increase with
increasing atomic number.
(b) Y would have an ionization potential betwee
those of X and Z.
© Z would have the highest ionization potential.
(d) Y would have the highest ionization potential.​

Answer 1

Answer:

option a.

Explanation:

Hope this may help you...

Answer 2

Answer:

(b) is true

Explanation:

X, Y and Z belong to same group. While going down the group ionization potential decreases. Thus, Ionization potential of Y is between those of X and Z.
