Three elements X, Y, and Z have atomic numbers 19, 37, and 55 respectively. Then the correct statements(s) is/are

Question

Three elements X, Y, and Z have atomic numbers 19, 37, and 55 respectively. Then the correct statements(s) is/are (A) their ionization potential would increase with increasing atomic numbers (B) Y would have an ionization potential between those of X and Z (C) Y would have the highest ionization potential (D) Z would have the highest ionization potential

Tardigrade Admin · Accepted Answer

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.

Q. Three elements X, Y, and Z have atomic numbers 19, 37, and 55 respectively. Then the correct statements(s) is/are

their ionization potential would increase with increasing atomic numbers

Y would have an ionization potential between those of X and Z

Y would have the highest ionization potential

Z would have the highest ionization potential

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.
