Ag+ + e- --> Ag
-3 electrons are gained,i.e,3 electrons are lost by Al and 3 electrons are gained by the other atom nearby.
Only one electron lost.
Mg 2.8.2 likes to lose 2 electrons to become Mg 2.8, when it loses them it becomes an Mg 2+ ion.
Two.
Oxidation is a loss of electrons. Mg2+ has lost two electrons from it's elemental state, and is thus said to be oxidised.

They are lost. If it has a plus sign beside the ion charge, that means the atom loses electrons. But if it has a negative sign for the ion charge, that means that the atom gains electrons.
An electron beam is shot at the Cu atoms, from an electron gun, this knocks out electrons meaning the overall charge of the atom becomes positive as negative electrons have been lost.
calcium ions that has lost electrons. It will give away electrons.
Magnesium that has lost 2 electrons.
Two.
An element you have a +2 charge It is had lost electrons. It would have to lose the same number of electrons that its positive charge is. So it would have lost 2 electrons.
it should lose 3 electrons
A metal ion is a metal atom that has either lost or gained an electron (although most metals tend to lose electrons rather than gain them). Any atom that has lost or gained one or more electrons is called an ion. A metal ion is thus a metal atom with a charge. Some examples are Fe3+ (iron with a plus three charge, or that lost three electrons), Ag+ (silver ion with a plus one charge) and Cu2+ (copper with a plus 2 charge).
i think it can but does not tell u if u have lost or gained half a pound
