Electron Configuration

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating how many electrons occupy each energy level and sublevel.

Front

How many electrons can the s orbital hold?

Back

The s orbital can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons in the p orbital?

Back

The p orbital can hold a maximum of 6 electrons.

Front

How many electrons can the d orbital hold?

Back

The d orbital can hold a maximum of 10 electrons.

Front

What is the Aufbau principle?

Back

The principle that electrons occupy the lowest energy orbitals first before filling higher energy orbitals.

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals (orbitals of the same energy) singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

No two electrons in an atom can have the same set of four quantum numbers; thus, an orbital can hold a maximum of 2 electrons with opposite spins.

Front

What is the electron configuration for Calcium?

Back

Front

How many different types of orbitals are there in the second energy level (n = 2)?

Back

There are 2 types of orbitals: s and p.
