### ml(cursive)

how do I change the number of electrons concerning the orbital being ml=-1?

I'm not sure what you're asking, but if you mean how do you know how many electrons ml could be refering to, that number is always 2. This is because ml refers to a sublevel within an orbital s, p, d, or f. And no matter how many sublevels they have (1,3,5,7), each sublevel can only hold 2 electrons.

Hi. ml determines the orientation of the orbital and each orbital can hold a maximum of 2 electrons. If the configuration is 2p for example, that means there are three possible orientations: ml = -1, ml = 0, ml = 1. Each orientation can have 2 electrons max.

I'm not sure if I understood your question, but I'm assuming you're asking how to determine the number of electrons given the ml value. If ml is given, we already know the sublevel, which contains two electrons with a spin up and spin down. If we were only given the n value like n=2, we wouldn't really know if we're talking about the s orbital or p orbital, but in this case I'm pretty sure we do.
