Question

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

Explanation:

In a water molecule ($H_2O$), hydrogen and oxygen atoms share electrons. Covalent bonds form when atoms share electrons to achieve a stable electron - configuration. Dispersion forces are intermolecular forces, not bonds that hold atoms within a molecule. Nuclear bonds hold particles within the nucleus. Hydrogen bonds are intermolecular forces between water molecules, not the bonds within a single water molecule.

Answer:

B. covalent bond
