Question

The two electron in a helium atom occupy (s) and have electron spin

Answer 1

Answer:

Two electrons in a helium atom occupy

An example is the neutral helium atom, which has two bound electrons, both of which can occupy the lowest-energy (1s) states by acquiring opposite spin. As spin is part of the quantum state of the electron, the two electrons are in different quantum states and do not violate the Pauli exclusion principle
