What is the chemical formula for Sodium Chloride (Salt)?
NaCl
Sodium loses one electron to form \(\text{Na}^{+}\) and chlorine gains it to form \(\text{Cl}^{-}\). The +1 and -1 charges combine in a 1:1 ratio, giving the formula NaCl.
The other options are stoichiometrically impossible — sodium is monovalent and chlorine is monovalent, so subscripts of 2 are not chemically valid.
