If an atom of neon absorbed energy what would initially happen to its outermost electrons?

The outermost electrons would reach its full shell. It would also become more negative in charge.

Explanation:

Since there are 7 electrons, gaining energy(by electrons) would complete the outer layer with 8 valence electrons. So the charge would be more negative, and also reaching a full shell. It would also become stable and not want more electrons.

Hope this helps!

n has four pairs of electrons in the valence shell, electrons repel one another ,n has 7 protons in its nucleus, and since n has 7 protons, it must fill the second shell, giving it 4 pairs of electrons. the electrons form 3 bonds and 1 lone pair of electrons. each pair of electrons repels the other pairs, so they are equally far apart.

so all of the above

4
