What is the significance of the Pauli Exclusion Principle in electron configurations?

No two electrons in an atom can have the same set of four quantum numbers.

How do you determine the number of valence electrons in an atom?

By looking at the highest principal energy level in the electron configuration.

What is the electron configuration for an atom with 12 electrons?

1s² 2s² 2p⁶ 3s² 3p⁴ (Magnesium)

What is the difference between the ground state and excited state of an atom?

Ground state is the lowest energy configuration, while excited state has one or more electrons in higher energy levels.

What is the electron configuration for an atom with 17 electrons?
