What is an orbital?

What is / ?

What is \ ?

What is the difference between / and \?

What is O (1s)?

What is O (2s)?

What are O O O (2p)?

What is the difference between O (1s) and O (2s)?

Is there a difference between O (2px), O (2py), and O (2pz)?

If so, what is the difference?

Do the spins of the first electrons in O (2px), O (2py), and O (2pz) need to be different, the same, doesn't matter?

What is the path of the electron in the orbital?

Why can the 2p orbital have 6 electrons when the 1s and 2s orbitals can only have 2?
