electron Configuration flashcard practice

Front

What is the electron configuration of an oxygen atom?

Back

1s² 2s² 2p⁴

Front

What does Hund's rule state?

Back

Orbitals of equal energy are each occupied by one electron before any is occupied by a second electron, and all electrons in singly occupied orbitals must have the same spin.

Front

How many electrons can the first energy level (s level) hold?

Back

2

Front

Which electron configuration describes a transition metal?

Back

The configuration is \lceil Ar \rceil 4s² 3d¹⁰.

Front

What atom has the electron configuration 1s² 2s² 2p⁶ 3s² 3p¹?

Back

Aluminum

Front

What is the maximum number of electrons that can occupy the p orbitals in a given energy level?

Back

Front

What is the Pauli Exclusion Principle?

Back

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

Front

What is the Aufbau principle?

Back

Electrons occupy the lowest energy orbitals first before filling higher energy orbitals.
