+3
It doesn't. Aluminium is a metal and so it LOSES electrons. Its electronic structure is 2,8,3 and so in order to attain the electronic structure of a noble gas (2,8 or 2,8,8) it either has to lose 3 electrons or gain 5 in the utermost orbit. Obviously it is much easier to lose just three, and so aluminum loses three electrons to form an Aluminium ion with a charge of 3+.
Aluminum, in its attempt to form a complete electron shell must lose 3 electrons to have an electron configuration that is isoelectronic with Neon. Because it loses the necessary three electrons, it forms a +3 cation.
Aluminum ions are formed whenever an electron is removed or translocated from an electron orbital.
Al3+ Al3+

Al3+
two are lost
gain one electron to form fluoride anion
Aluminum has 3 valence electrons.
an aluminum atom will lose the 3 electrons on its outer shell 2 for an aluminum ion.
1200 for that one, its very difficult
Aluminium lose 3 electrons and form the cation Al3+.
Chromium lose 6 or 3 electrons.
Calcium loses two electrons to form the cation Ca2+.
None.Calcium loses 2 electrons to form an ion.
