What is the formula for sodium chloride?

The chemical formula for sodium chloride is NaCl. That’s the stuff we all know as table salt. The 'Na' is the symbol for the element sodium. The 'Cl' is the symbol for chlorine. It’s a pretty straightforward formula. It shows a simple one-to-one ratio between the two elements. Basically, a sodium atom donates an electron to a chlorine atom. This creates oppositely charged ions that attract each other. So, when you see NaCl, you're just looking at the scientific name for everyday salt. Hope that helps you out
