Lithium forms a +1 ion because it loses one electron, making the ratio of electrons:protons unbalanced by losing one electron. the ratio is now 2e:3p.
Oxygen forms a -2 ion because of a different reason. It gains 2 electrons rather than losing them.

Hydrogen bonding occurs between a hydrogen atom and an electronegative atom (e.g., oxygen, fluorine, chlorine). The bond is weaker than an ionic bond or a covalent bond, but stronger than van der Waals forces (5 to 30 kJ/mol). A hydrogen bond is classified as a type of weak chemical bond.
