Explain the type of bonding in sodium chloride.

The type of bonding in sodium chloride is ionic. This sodium atom loses its outer most electron to complete its outer most shell to form a sodium ion (positive) and donates it to the chlorine atom which accepts its to form a chloride ion (negative) and complete its outer shell. This results in electronic static attraction between adjacent sodium and chloride ions.
