400
An ionic bond is an electrical attraction between these two types of atoms.
What is a positively and negatively charged ion?
500
Na+ (Sodium) and Cl- (Chlorine) combine using this type of bond. Explain why.
What is an ionic bond because Sodium transfers an electron to Chlorine which allows Sodium to become a positive ion and Chlorine a negative ion?
