Why can’t molecules with the following formulas exist?

Why can’t molecules with the following formulas exist? The number of bonds that some atoms form is shown below. A structure which requires these atoms to exceed these numbers of bonds is not possible because it requires that the atoms exceed the number of electrons that fit into its outer shell.

Why is AlH3 a covalent hydride?

Covalent hydrides are primarily compounds of hydrogen and nonmetals, in which the bonds are evidently electron pairs shared by atoms of comparable electronegativities. The neutral hydrogen compounds of aluminum and gallium are elusive species, although AlH3 and Ga2H6 have been detected and characterized to some degree.

What is the name for Sr3 PO4 2?

Strontium phosphate
Strontium phosphate | Sr3(PO4)2 – PubChem.

Why is CH5 not possible?

Another interesting aspect is that CH5+ shows a peculiar form of chemical bonding: there are five protons but only four available valence orbitals! Thus, it is not possible that one electron pair, or one localized orbital, respectively, is located in between the carbon nucleus and each proton like in methane, CH4.

How do you calculate aluminum?

Aluminum has an atomic weight of 26.9815 in Daltons or grams per mole (g/mol). This means if you have a certain number of moles of aluminum, you can multiply it by the atomic weight to figure out how many grams per mole of aluminum you have. This accounts for the weight of aluminum in its pure form.
