Electron Configuration

Front

What is Electron Configuration?

Back

The distribution of electrons in an atom's orbitals, which determines its chemical properties.

Front

What does the Pauli Exclusion Principle state?

Back

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

Front

What is the Aufbau Principle?

Back

Electrons occupy orbitals in order of increasing energy, filling lower energy orbitals before higher ones.

Front

What is Hund's Rule?

Back

Every orbital in a given subshell is singly occupied by electrons before any orbital is doubly occupied.

Front

How many electrons can the s subshell hold?

Back

2 electrons.

Front

How many electrons can the p subshell hold?

Back

6 electrons.

Front

How many electrons can the d subshell hold?

Back

10 electrons.

Front

How many electrons can the f subshell hold?

Back

14 electrons.

Front

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

Back

2 electrons.

Front

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

Back

8 electrons.
