Question

How does magnesium ion and neon have same no of electrons

Answer 1

Magnesium has 12 protons and an electron arrangement of 2,8,2. ... Neon has no charge as it has the same number of protons and electrons, as it has not gained or lost electrons, as it has an electron arrangement of 2,8 because it is in group 18 of the periodic table and its valence shell is complete.

Flow me because I gave you a answer.
