Sodium is nonpolar, as is any element on its own.
No, Na-S bond is ionic as sodium (Na) is a metal and sulfur (S) is a non-metal. Ionic bonds form between metals and non-metals, where electrons are transferred from the metal to the non-metal to complete their outer electron shell.

Sodium chloride is an ionic molecule because it is formed by the transfer of electrons from sodium (Na) to chlorine (Cl). The resulting ions, Na+ and Cl-, are held together by strong electrostatic forces in a crystal lattice structure.
