If Sodium (Na) and Chloride (Cl) were to bond, what has to happen for atoms to combine (to be happy) and what kind of bond would this be?
Sodium has 1 valence electron which it can give up making it a positively charged atom and Chlorine has 7 valence electrons which it can accept an electron making it a negatively charged atom--opposites attract. since electron is being transferred it forms an Ionic bond.
