Question

question 2
covalent bonds form when
two hydronium ions are attracted to each other.
two hydrogen atoms share electrons with one oxygen atom.
a molecule of water becomes an ion.
two molecules of water share electrons.

Explanation:

Covalent bonds form when atoms share electrons. In water (\(H_2O\)), two hydrogen atoms each share electrons with one oxygen atom. Hydronium ions (\(H_3O^+\)) are formed through a different process (protonation of water), a water molecule becoming an ion is not about covalent bond formation in the context of the molecule's structure, and water molecules do not share electrons with each other in the way described for covalent bond formation within a single molecule.

Answer:

two hydrogen atoms share electrons with one oxygen atom.
