Question

how do ionic bonds differ from covalent bonds?
electrons are shared in a covalent bond.
electrons are transferred in a covalent bond.
protons are transferred in a covalent bond.
protons are shared in a covalent bond.

Explanation:

Ionic bonds involve electron transfer (e.g., metal losing electrons to non - metal), while covalent bonds involve electron sharing (e.g., two non - metals sharing electrons). Protons are in the nucleus and not involved in bonding in this context.

Answer:

Electrons are shared in a covalent bond.
