Answer:

magnesium= +2

aluminum= +3

phosphorous= -3

lithium= +1

fluorine= -1

Explanation:

As fluorine having seven valance electrons in its outer most shell with atomic number nine. And for completing its outer most shell it needs one more electron that is why it form ion of -1 value.

Now  Aluminum has three electrons in its outer most shell with atomic number 13. So it need to lose these three electrons in order to be in stable state that is why it have ion in +3 state.

Same rule apply for other elements too.
