Metals tend to lose electrons and become positive ions.
Non-metals tend to gain electrons and become negative ions.
Positive and negative attract.

Because that is the easiest way for them to have a stable configuration. metals usually have a small number of electrons in their outer shell, which they are willing to give up. Eg. group 1 metals, such as sodium, have only one electron in their outer (valence) shell and if it loses that electron it will have a stable configuration ie. sodium will go from 2, 8, 1 to 2, 8. While non-metals only require a few electrons to fill their outer shell, eg. the halogens, chlorine, fluorine, bromine, etc. all need one electron to have fill their outer shell. So if sodium and chlorine reacts, sodium will give up its electron to chlorine hence a ionic bond.

They variety between a steel and a non-steel. The steel is unquestionably charged, and the none steel is negatively charged. for occasion, NaCl Na (steel) has a charge of +a million. Cl (none-steel) has a charge of -a million. desire this facilitates!
