How many electrons can occupy a single molecular orbital?
and Alumimum is a group 3A metal, Which ion does A1 typically form? I'm thinking Al3+
Your first question depends on the molecule involved and how it is bonded. Hybrid molecular orbits can be formed.
Now in an atom, there are electron orbitals of mostly fixed shape and predictable energy levels and vacancies.
In a particular energy level there can be up to 2n^2 electrons. In a particular orbital, and there are in any energy level, up to 2n-1 orbitals, or a total of 2(2n-1) total electrons in that energy level.
I recommend you see your text on this, I suspect there is a chart showing the filling of the electrons into energy levels and orbitals.

Yes, aluminum forms the +3 ion.
Ah, the mysteries of electrons and their orbital antics! It's like a never-ending carnival of buzzing particles.
As for your first question, the number of electrons that can occupy a single molecular orbital depends on the molecule itself and how it's bonded. It's like a dance party – the more space available, the more electrons can come and shake their tiny little booties. So, to give you a specific number would be like trying to predict how many clowns can fit in a Volkswagen Beetle. It varies, my friend!
Now, onto the enchanting world of aluminum. Ah, such a shiny and versatile metal! In its natural state, aluminum likes to form a +3 ion. It's like a metal with a little extra sparkle, you know? So, you're on the right track with your guess of Al3+. Just imagine aluminum strutting its stuff with a little positive charge to make things interesting.
The maximum number of electrons that can occupy a single molecular orbital depends on the type of molecular orbital. In general, a single molecular orbital can hold a maximum of 2 electrons, one with a spin-up (+1/2) and one with a spin-down (-1/2) orientation. This is known as the Pauli exclusion principle. However, in some cases, molecular orbitals may have a higher degeneracy and can accommodate more than 2 electrons.
Regarding aluminum (Al), it is indeed a group 3A metal and typically forms the Al3+ ion. Aluminum has three valence electrons, which it can lose to achieve a stable electron configuration with a full outer shell. As a result, aluminum typically loses these three valence electrons to form the Al3+ ion, which has a 3+ charge due to the loss of three electrons.
To answer your first question, the number of electrons that can occupy a single molecular orbital depends on the type of orbital and the bonding situation. In general, a single molecular orbital can hold a maximum of 2 electrons, following the Pauli exclusion principle.
As for your second question, aluminum (Al) is indeed a group 3A metal. And typically, aluminum forms the Al3+ ion. This means that aluminum loses its three valence electrons to achieve a stable octet configuration.
