Question

Whivh element's ionization enthalpy is 800kj per mol

Answer 1

Ionization energy decreases as we move down a group because: As we move down, a new full energy level is being added. More electrons means more repulsion. This creates the shielding effect where the addition of the shells, shields the outer electron from receiving the nucleic charge.

Answer 2

Explanation:

First, second & third ionization energies are 737, 1045 & 7733 KJ,,mol respectively. ... Which element exhibits the successive ionization energies given in the table ...
