is Aluminum wrotten with a 2 behnd it?Aluminum is not a diatomic atom, which is to say, in it\'s equilibrium state it has only one atom, written Al. As an ion, aluminum has a charge of 3+, and may have a subscript of 2 when written in an ionic formula (i.e., aluminum oxide: Al2O3).Are you asking if it\'s a diatomic molecule? Because then the answer would be no. Aluminum is a metal. The only diatomic molecules are Hydrogen, Nitrogen, Oxygen, Chlorine, Flourine, Bromine and Iodine. And even those are only written when they are by themselve and not part of a chemical compound.No, you\'re thinking of diatomic molecules like dinitrogen and dihydrogen which come in pairs because forming a covalent bond with another atom fills up their electron shell which is what makes them most stable. Metals don\'t tend to form covalent bonds in bulk but have a kind of ionic bond. You could search for \'metallic bonding\' and I imagine some helpful sites would appear. Basically, the electrons are shared, that\'s what makes metals conductors of electricity. kind regardsalminum has an atomic number of 13 and it gives has electrons in its outer most shell and so aluminium is written as al+3 and the formulae for aluminium blending with say oxygen is Al2o3 where aluminium gets al the three molecules while oxygen gets al two molecules this is expalined by the criss cross method in chemistry for compound formulaesNo. Aluminum is a metal, which means that its structure is essentially a lattice of metal cations with very loosely-held electrons passing rather freely between them.Other related question
