Question

which type of bond holds atoms together in a water molecule?
nuclear bond
dispersion forces
hydrogen bond
covalent bond

Explanation:

In a water molecule ($H_2O$), hydrogen and oxygen atoms are held together by covalent bonds. Covalent bonds involve the sharing of electron - pairs between atoms. Hydrogen bonds are intermolecular forces between water molecules, not the bonds within a single water molecule. Dispersion forces are also intermolecular forces. Nuclear bonds hold the nucleus of an atom together, not atoms in a molecule.

Answer:

D. covalent bond
