* Ionic Bonding: Salt (NaCl) is formed through an ionic bond. This happens when sodium (Na) loses an electron to become a positively charged ion (Na+) and chlorine (Cl) gains an electron to become a negatively charged ion (Cl-).

* Neutral Compound: The resulting positive and negative charges attract each other, forming a neutral compound. The overall charge of salt is zero.

Therefore, salt itself does not have a negative charge.
