Question

which bonds are found inside a water molecule, between hydrogen and oxygen?
hydrogen bonds
electronegative bonds
proton bonds
covalent bonds

Explanation:

A water molecule ($H_2O$) consists of an oxygen atom covalently bonded to two hydrogen atoms. Covalent bonds form when atoms share electron pairs, which is the intramolecular bond holding H and O together in a single water molecule. Hydrogen bonds are intermolecular (between separate water molecules), while electronegative bonds and proton bonds are not valid bond types in this context.

Answer:

covalent bonds
