Number of electrons are lost by an atom in a chemichl reaction
Often there are the same number of electrons as there are protons. Exceptions to this are called ions, which have gained or lost an electron (can't be a proton lost or gained, that would change the element).
Aluminium will lose 3 electrons to form Al3+ ions.

It is called Oxidation number.
The oxidation number of an ionic atom or molecule is the number electrons that it has lost or gained.
Electrons are both gained and lost. Electrons are both gained and lost.
