Answer 1

➠ AnSwer :-

➝ 1st answer :-

• Effective nuclear charge implies that the net(effectice) force experienced by the electrons in the outermost shell
• If Effective nuclear charge increases then the outermost electrons will be pulled stronger by the nucleus and it will require more energy to take out that electrons. So, the ionization energy increases.

➝ 2nd answer :-

• As with the alkali metals, the atomic and ionic radii of the alkaline earth metals increase smoothly from Be to Ba, and the ionization energies decrease.
• With their half-filled ns orbitals, the alkali metals have a significant affinity for an additional electron.
