Quantum numbers x,y,z

[Adam Kramer 1A]

When we are writing quantum numbers such as 2Px2, does it matter if we put x or y or z, or are those just chosen at random when we are writing them?

[Vanessa Chuang 4F]

The orientation of x, y, and z are completely subjective and based on how you decide to view it. So in the context of when we are writing them, you just pick the way you want to assign them and stick with that assignment for the rest of the problem.

[Sarah Nichols 4C]

For the p subshell, x,y, and z are arbitrary because they are all symmetrical
