Actinides and lanthanides lose electrons and form cations.

It is going to lose electrons
The elemental state of aluminum tends to lose electrons. Its ionic state is 3+ which means it is most likely to lose up to 3 electrons.
Since this is a metal it is going to lose electrons. Metals lose the electrons while nonmetals gain electrons.
It needs to gain 3 electrons than to lose 5 electrons. So phosphorus has to gain 3 electrons.

lose
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
Metals usually lose electrons, this is why many charges are positive.
Lose electrons is oxidation. To gain electrons is reduction.
Beryllium lose electrons (2).
It can both gain and lose electrons depending on the different elements. With hydrogen, it gains electrons to produce hydrogen sulphide and it will lose electrons with oxygen to produce sulphur oxides. Generally it will tend to gain electrons as it is in group 16 of the elements and so is quite negatively electrovalent but against a more negatively electrovalent elements it can be forced to lose electrons unwillingly as in the case of oxygen. Even though oxygen is also in group 16, sulphur is an order below oxygen and therefore less negatively electrovalent that oxygen.
Polonium lose electrons.
lose three electrons
sn lose 4 electrons
Sodium lose electrons becoming a cation.
Magnesium lose two electrons to form MgF2.
