In a Lewis structure, what do you do with the total number of valence if your ion is 2- charged?

a) Divide the valence number by 2
b) Multiply the valence number by 2
c) Subtract 2 from the valence number
d) Add 2 to the valence number

Select all of the statements which are true. electrons are located in shells or orbits around the atom. electrons orbit slowly around the atom. electrons travel in one flat path around the nucleus of an atom. the valence of an atom is determined by the number of electrons in the atom's outermost shell.
