Question

what best explains whether bromine (br) or neon (ne) is more likely to form a covalent bond? bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and

Explanation:

Covalent bonds form when atoms share electrons to achieve a full valence shell (8 electrons, octet rule). Bromine (Br) has 7 valence electrons, so it needs 1 more electron to complete its octet, making it likely to share electrons in a covalent bond. Neon (Ne) is a noble gas with a full 8-valence-electron shell, so it is stable and does not form covalent bonds.

Answer:

Bromine forms covalent bonds because it has seven valence electrons, but neon has eight valence electrons and is stable, so it does not form covalent bonds.
