fe+3
Aluminum has trivalent cation. It is Al3+
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
Al+3 aluminum
The difference between Al and Al+3 is that the ion has lost 3 electrons, therefore it has 3 more protons than electrons, hence granting it a charge of +3.
An Al ion would have a +3 charge.
The Al (aluminum) ion exists in the 3+ state.
fe+3
The phosphide ion is stable
It would become an Aluminum ion that has a 3+ charge
O = 2- Al = 3+ N = 3- I = 1- Mg = 2+ Ba = 2+ S = 2- K = 1+
The formulas of the most common ions of these elements are Al+3 and Cl-1.
Aluminum has trivalent cation. It is Al3+
Ga is a 3+ and As is a 3- so it is Ga3As3 which is GaAs
The stable ion of aluminum is Al 3+, which means it has three fewer electrons. The aluminum atom has shed its outer shell of 3s2 3p1 and has an electron configuration equal to that of Neon, or 1s2 2s2 2p6.
The aluminum ion is Al^3+ and the sulfate ion is SO4^2-
Aluminum loses 3 electrons. Since electrons have a negative charge losing them would make the aluminum atom lessnegative, which is positive. Hence, Al+3
