Sodium chloride, which is also known as salt, is a white color crystal with the molecular formula NaCl. Sodium chloride is an ionic compound. Sodium is a group 1 metal, thus forms a +1 charged cation. Its electron configuration is 1s 2 2s 2 2p 6 3s 1.odium and potassium are group 1 metals, which have the capability to make +1 cations. Chloride is the -1 anion made by group 7 element, chlorine. Since group 1 elements are electropositive and group seven elements are electronegative, their electronegativity difference is larger. So they form ionic bonds.
