a million.0 Potassium is extremely electropositive ingredient with low ionization power. This property makes the outer valance electrons ejection particularly common with electric voltage. As you be conscious of electric impulses are using bypass of electrons 2.0 4 moles of Al reacts with 3 moles O2 giving Aluminum oxide. this suggests that 8 moles of Al choose for six moles of O2 3.0 team III era iv, probable the ingredient is Ga and the Oxide is Ga2O3 4.0 1s2 2s2 2p6 3s13Px1
