Quantum numbers

Why is it that no two electrons in the same atom have the same four quantum numbers?

The set of four quantum numbers is like an address for each electron. Two electrons can't occupy the same space just like how two people can't occupy the same spot, which is why no two electrons can't have the same four quantum numbers in an atom.

This is due to the Pauli-exclusion principle. Also, it's important to note that an orbital can only contain a maximum of 2 electrons, so the two electrons must have opposing spins.

They can not exist in the same place at the same time. It is also how we do not know its exact position in the shell but we know its there.

To add onto Cassidy's comment above, it's important to know that although each orbital can hold a maximum of 2 electrons, each energy shell can have more than 2 (aside from s) because there are multiple orbitals in each shell.
