Ok an atom loses an electron becomes positive-atom gainin electron becomes negative? Is that correct? thats w/ 1 electron in outer shell of one atom and the other atom receiving an electron to fill its outer shell

That is correct. Electrons have a negative charge to them. Atoms typically have an equal number of protons, which are positive, to electrons. This makes the atom neutral. By losing an electron, and taking away a negative force, you weigh the atom on the positive side making it more positive. If you have an neutral atom and then gain another electron then you are adding a negative force which weighs it on the negative side.
