Yes, it is correct - NaCl is a formula unit of sodium chloride; ionic compounds hasn't a true chemical formula.
The formula unit -NaCl - (not a molecule) contain two atoms.
Today NaCl is considered the formula unit of sodium chloride, not the true chemical formula of the molecule; NaCl form very complex lattices, as other ionic salts.
Two atoms in the formula unit (not molecule): Na and Cl.
In the formula unit (NaCl) are 28 protons.
The molecular mass of NaCl (as formula unit) is 58,44 g.
The term molecule is not adequate for sodium chloride; the recommended term is formula unit.
The formula unit of NaCl (sodium chloride) contain 2 atoms.
The formula unit of sodium chloride (NaCl) contain 28 protons.
A formula unit is a unit that is made up of a metal and a nonmetal. (ex: NaCl) but i think it can also be really big (ex: NaHCO3) A molecule is molecular - only molecular (ex: H2O)
The term molecule is not adequate for sodium chloride because NaCl form large lattices. More exact is formula unit - NaCl.
The term molecule is not adequate for an ionic compound; correct is formula unit.60 g NaCl contain the equivalent of 1,026 formula units.
Wate is molecular , H2O. NaCl is giant ionic laattice and is not molecular when normally encountered. In terms of mass the formula unit of NaCl is greater than than the molecular mass of water.
