It is called a "metallic bond"
hydrogen bonds, which are very easy to break.
This type of bond exists in proteins, it is amide bond formed between nitrogen atom of one molecule and carbonyl carbon of 2nd molecule , as R-CO-NH-CH(R)-CO-
An sp4 bond exists between the carbon atoms in diamonds.
A negative charge exists because of the electronegativity of oxygen.
'Covalent'.
Covalent bond exists
Covalent bond exists between a carbon atom and a chlorine atom.
Single covalent bond :)

Peptide bonds.
In any compound, if there exists a bond between sodium and oxygen, it is ionic.
A hydrogen bond.
