Explain all ways your atom and symbol for it would change if you removed 2 electrons from the atom

Each atom/element has an electron configuration

The electron configuration shows the energy level of the electron

Each electron configuration has 4 quantum numbers, namely n, l, ml, and ms

We make an example of the element Mg which is in group 2 with the atomic number 12

Electron configuration of Mg: [Ne] 3s² or 1s² 2s² 2p⁶ 3s²

if Mg removes 2 electrons then Mg will form a positive ion (cation) Mg²⁺

This cation is included in the monatomic ion because it is formed from one element (in contrast to the polyatomic ion, which is formed from two or more elements such as SO₄²⁻, ClO₃⁻)

Electron configuration of Mg²⁺ : 1s² 2s² 2p⁶

So atoms can be positively or negatively charged depending on removing or attracting electrons
