Question

in a covalent bond, electrons are __________. *
o shared
o lost
o gained
o destroyed

nacl is the chemical formula for what? *
o water
o chlorine gas
o sodium chloride
o sodium metal

in sodium chloride (nacl), which atom loses an electron? *
o chloride
o sodium
o salt

Explanation:

1. In a covalent bond, atoms share electrons to achieve a stable electron - configuration.
2. The chemical formula NaCl represents sodium chloride. Sodium (Na) donates an electron to chlorine (Cl) to form an ionic bond in sodium chloride. Sodium has one valence electron and is likely to lose it to gain a stable noble - gas configuration.

Answer:

1. A. shared
2. C. sodium chloride
3. B. sodium
