Oh, dude, aluminum loses electrons like it's trying to shed some weight before summer. It's all like, "See ya, electrons, I don't need you weighing me down." So yeah, aluminum loses electrons to become positively charged because it's all about that positive energy, you know?
Aluminum has 13 electrons. To achieve a noble gas electron configuration like neon, aluminum needs to lose 3 electrons to have the same electron configuration as neon (10 electrons). This results in the formation of the Al3+ ion.
Silicon (Si) can gain or lose 4 electrons. It can either gain 4 electrons to have a stable octet configuration or lose 4 electrons to achieve a stable configuration.
Selenium may lose 2, 4 or 6 electrons and may gain 2 electrons.
Metals lose electrons, nonmetals gain electrons.
Sulfur must gain two electrons.
Aluminium will lose 3 electrons to form Al3+ ions.
Aluminium should gain 5 electrons or lose 3 electrons. It will normally lose 3 electrons to form Al3+ ion, rather than gaining 5 electrons and forming Al5- ion.
Lose
Aluminium lose 3 electrons and form the cation Al3+.
When atoms lose or gain electrons, they form ions. These are charged particles.
Se will gain electrons
Lose electrons is oxidation. To gain electrons is reduction.

If you mean Metals... No, they do not gain electrons, they actually lose electrons because it is a lot easy for them to lose them so they can gain stability much faster.
it loses electrons
Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.
