Electron Configuration- Honors Unit 4

Front

What is electron configuration?

Back

The distribution of electrons in an atom's orbitals, indicating the energy levels and sublevels occupied by electrons.

Front

What are the four types of orbitals?

Back

s, p, d, f

Back

It indicates that there are 2 electrons in the 1s orbital.

Front

How many electrons can the s orbital hold?

Back

2 electrons.

Front

How many electrons can the p orbital hold?

Back

6 electrons.

Front

How many electrons can the d orbital hold?

14 electrons.

Front

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

Back

18 electrons.

Front

What is the Aufbau principle?

Back

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

Front

What is Hund's rule?

Back

Electrons will fill degenerate orbitals singly before pairing up.
