How many electrons does aluminum gain to form an ion?

Answer 1

+3

Answer 2

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+.

Answer 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.

Answer 4

Aluminum ions are formed whenever an electron is removed or translocated from an electron orbital.

Answer 5

Aluminum typically loses 3 electrons to form an ion with a 3+ charge.

Answer 6

Al3+ Al3+

Answer 7

+3

Answer 8

Al3+
