Question

write the formation of aluminium ions

​

Answer 1

Answer:

Aluminium atoms have to lose 3 valence electrons in order to have full outer shells, making them “stable” (or like my chemistry teacher said, “happy”). Therefore, aluminium ions have a charge of 3+ for they lost 3e-, each of which has a charge of 1-.

The equation for this is: Al→Al3++3e−
