Question

****Really Need Help/ I Give Medals****

1) There is a large jump between the first and second ionization energies of lithium There is a large jump between the second and third ionization energies of magnesium. Explain why this occurs.

2) Describe the trends in first ionization energy within groups and across periods in the periodic table. Provide examples.

3)Explain how ions form, as well as the terms used to describe them. Explain how the elements of different groups form ions. Provide examples.

Answer 1

It's easier to remove a sole, valence electron than an electron from a full/complete valence shell.

The initial ionization of Li leaves it with an electronic configuration of He, so because of the stability of the full 1s orbital, it takes more energy to remove an additional electron.

Similarly with Mg, the second ionization leaves it with electronic configuration of Ne, the configuration is more stable than before.
