Hi there! Sodium Chloride (NaCl) can't be polar. In order for a compound to be polar, it must be covalently bonded, wheras Sodium Chloride is ionically bonded! Ionic bonds are where an electron is 'stripped' from one element and adopted by the other. Covalent bonds are where the electron is shared! read more
Sodium chloride, or NaCl, is an extremely polar ionic compound, according to Kent Chemistry. Sodium chloride is composed of an Na+ cation and a Cl- anion. In a simple molecule, such as NaCl, the whole molecule is polar if the bond is polar. read more
Sodium chloride is ionically bonded. An electron has transferred from sodium to chlorine. Sodium has an electronegativity of 1.0, and chlorine has an electronegativity of 3.0. That's an electronegativity difference of 2.0 (3.0 – 1.0), making the bond between the two atoms very, very polar. read more
