Sodium gives away an electron, and forms a positively charged ion. (MORE protons than electrons)
Chlorine accepts an electron, and forms a negatively charged ion. (MORE electrons than protons)

Opposite charges attract forming an ionic bond. Ionic compounds are neutral.

Ion ­ a charged atom

Acids are ionic bonds.
