3+
So from Al is formed the Al3+ion by oxidation (electron donation to e.g. oxygen)
Al only forms 1 ion with a charge of +3.
An Al ion would have a +3 charge.
+3
The Al (aluminum) ion exists in the 3+ state.
Al 3+.
The charge on aluminium is 3+ also written as Al 3+
Al(FlO3)3. Al has a charge of +3 and FlO3 has a charge of -1 so 3 fluorate ions are needed for every Al ion to balance the charge of the compound. ***extra--if you didn't know what fluorate was.... A well known ion, ClO3 (the chlorate ion), has a charge of -1. Fl is in the same group as Cl so the fluorate ion will have the same number of oxygens and the same charge as ClO3.
The aluminium ion is Al(3+).
Aluminium, Al
S(2-) : sulfide ion Al(3+) : aluminum ion
Aluminum forms a cation with a 3+ charge, and the formula Al3+.
Iron is a metal element. Atomic number of it is 26.
