The chemical formula of table salt, NaCl, tells us what about the atomic bonding of this molecule?

A) The Sodium (Na) has to be present before the Chlorine (Cl)
B) The structure of the Sodium (Na) and the Chlorine (Cl) is a triangle
C) Exactly 1 atom of Sodium (Na) is bonded with 1 atom of Chlorine (Cl).
D) Nothing can be determined without a visual guide first.

1 answer

The correct answer is:

C) Exactly 1 atom of Sodium (Na) is bonded with 1 atom of Chlorine (Cl).

The chemical formula NaCl indicates a 1:1 ratio of sodium ions to chloride ions, meaning that one sodium atom bonds with one chlorine atom to form table salt.
