I think answer should be Na

option A

Answer 2

The element with the given IP values is of group 1.

• It is given that the IP values of the element are 19, 190, 230, and 260 EV/atom.
• Now, we can notice that there is a large difference between the first and the second IP value, which means that after the removal of the first electron, it is difficult to remove the second electron.
• More energy is required for the removal of the second electron as compared to the energy required for the removal of the first electron.
• Thus, we can say that the element is from group 1 with only one electron in the valence shell.
