Sodium chloride (NaCl) formula unit has one chlorine atom.
If the formula unit is NaCl - 7 chlorine atoms.
Sodium chloride (NaCl) contain two atoms: 1 sodium and 1 chlorine.
There are 2 atoms (1 sodium, 1 chlorine) in each formula unit of sodium chloride.
7 atoms.
0 atoms. I'm guessing you are suggesting table salt, which is sodium chloride. Sodium chloride only contains sodium and chlorine and no oxygen.
Na is sodium Cl is chlorine NaCl is sodium chloride (table salt)
Common salt is sodium chloride (NaCl) which is composed of two atoms, one of sodium and one of chlorine.
The chemical formula of table salt (sodium chloride) is NaCl; the ratio is 1.
In one molecule of NaCl there are two ions, Na+ and Cl-.
Your phrasing is slightly off. It does not require ions to form sodium chloride; that compound is made from atoms of sodium and chlorine (one of each). Once the compound is formed, the sodium and chlorine then become ions, Na+ and Cl-.
Sodium chloride is a lattice. There are only two elements.
Halite is sodium chloride, NaCl; NaCl has in the molecule two atoms: 1 Na atom and 1 chlorine atom.
The number of atoms in 7.5 grams of sodium chloride is 1.55X10^23. Sodium chloride is more commonly known as salt or table salt.
