Electron Orbitals and Configurations Practice

Front

How many electrons can the first energy level hold?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is the electron configuration of an atom with 10 electrons?

Back

The electron configuration is 1s² 2s² 2p⁶.

Front

Which atom has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰?

Back

Zinc (Zn) has this electron configuration.

Front

What do you start an electron configuration with?

Back

You start with 1s².

Front

Which atom has the electron configuration 1s² 2s² 2p⁶ 3s² 3p⁶ 4s² 3d¹⁰ 4p²?

Back

Front

What is the maximum number of electrons in the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.

Front

What is the significance of the 's', 'p', 'd', and 'f' in electron configurations?

Back

They represent different types of atomic orbitals: 's' (spherical), 'p' (dumbbell-shaped), 'd' (clover-shaped), and 'f' (complex shapes).

Front

What is the Aufbau principle in electron configuration?

Back

The Aufbau principle states that electrons occupy the lowest energy orbitals first.

Front

What is Hund's rule?

Back

Hund's rule states that electrons will fill degenerate orbitals singly before pairing up.

Front

What is the Pauli Exclusion Principle?

Back

The Pauli Exclusion Principle states that no two electrons in an atom can have the same set of four quantum numbers.
