Answer:
• Hydrogen and oxygen atoms
Explanation:
Hydrogen and oxygen are nonmetals. They are most likely to share electrons and form a covalent bond.
A is wrong. Gold is a metal, so it will form metallic bonds.
O is wrong. Neon is a noble gas. It has a complete octet, so it is unlikely to form covalent bonds.
D is wrong. Mg is a metal, and Br is a nonmetal. They are more likely to form ionic bonds.
