→What is the relation between ionization potential and effective nuclear charge experienced by an electron in nth orbit?→ What is the general trend observed in ionization energy in alkali and alkaline earth metals?Useless answers will be reported✌️​

Answer»

➠ 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.
