How many electrons can each individual orbital hold?

Orbitals of equal energy are each occupied by one electron before any orbital is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin state. Noble-gas configuration refers to an outer main energy level occupied, in most cases, by eight electrons.

Explanation:

I hope this helps you.

Two electrons

Explanation:

Each individual orbital can hold a maximum of two electrons. Hope this helps :)

there is none because earth is stationary and flat.

i wish i could but this one is weird give me abc and i can solve it.
