Question

Which of the following have low IP and low EN value​

Answer 1

Answer:

In a period, as we move from left to right, the ionization energy increases. As we move along a period, the nuclear charge increases and the electrons are added into the same shell. Thereby the effective nuclear charge increases and size decreases. Therefore, the energy required to remove an electron increases.

Thus, alkali metals have the lowest I.P. and noble gases have the highest I.P.
