Highlight the element(s) that form cations with the same electronic configuration as Ne

Answer 1

The element(s) that form cations with the same electronic configuration as Ne are:

1. Sodium (Na+) - Sodium forms a cation by losing its outermost electron, resulting in a configuration of 1s² 2s² 2p⁶, which is the same as Ne.

2. Magnesium (Mg2+) - Magnesium forms a cation by losing its two outermost electrons, resulting in a configuration of 1s² 2s² 2p⁶, which is the same as Ne.
