What is Ionic Bonding?
An ionic bond is a type of chemical bond that involves a metal and a nonmetal ion
100
how is a covalent bond formed?
Having the same number of electrons
100
what is a multiple bond?
Chemical molecules are made up of two or more atoms bonded together.

The electrons in the (fill in the blank) of an atom are the ones which usually participate with chemical bonding?
Oter energy level
200
what happens when an ionic bond in formed by electron transfer between a metal and a nonmetal?
all the electrons are lost by the metal must be gained by the nonmetal.
