Question

sodium + chlorine yields sodium chloride. check out the model above. what information is provided by the model?
a sodium chloride is a salt.
b sodium chloride is a molecule.
c sodium chloride is composed of atoms.
d two atoms always combine to form a compound.

Explanation:

The model shows sodium (Na) and chlorine (Cl) atoms. Sodium chloride (NaCl) is formed from these atoms. Option A: The model does not show that NaCl is a salt. Option B: NaCl is an ionic compound, not a molecule (in the traditional covalent - molecule sense as shown in the model). Option D: The model only shows one example (Na and Cl), not a general rule that two atoms always combine. The model clearly shows that NaCl is made from Na and Cl atoms.

Answer:

C. Sodium chloride is composed of atoms.
