Answer 1

Mg\(^{2+}\) and O\(_2^{-}\) what is happening here?

Answer 2

i'm not that good at any kind of science. so i'm not sure. could you help me out? like step by step to help me understand? :)

Answer 3

Well, by definition, an \(\sf \color{red}{ionic~bond}\) is chemical link between two atoms caused by the electrostatic force between \(oppositely-charged\) ions in an ionic compound.
and \(\sf \color{blue}{covalent~bond}\) is a chemical bond that involves \(\color{orange}{sharing}\) a pair of electrons between atoms in a molecule
