Three elements X, Y, and Z have atomic numbers 19, 37, and 55 respectively. Then the correct statements(s) is/are
Options
- Atheir ionization potential would increase with increasing atomic numbers
- BY would have an ionization potential between those of X and Z
- CY would have the highest ionization potential
- DZ would have the highest ionization potential
Correct answer
B. Y would have an ionization potential between those of X and Z
Step-by-step solution
The elements X(19), Y(37) and Z(55) are the elements of same group (IA). As atomic number, increases, the ionization potential decrease down the group. Since, the position of Y is in between X and Z. Thus, the ionization potential of Y will also be in between X and Z.
