Electron Configuration & Orbital Diagrams

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 does the notation 1s² represent?

Back

It indicates that there are 2 electrons in the 1s orbital, which is the lowest energy level.

Front

How many electrons can the s sublevel hold?

Back

The s sublevel can hold a maximum of 2 electrons.

Front

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

Back

The p sublevel can hold a maximum of 6 electrons.

Front

What is the significance of the periodic table rows?

Back

Each row represents a principal energy level (n) for the electrons.

Front

What is the electron configuration for oxygen?

Back

1s² 2s² 2p⁴.

Front

What is the electron configuration for zinc?

Back

[Ar] 4s² 3d¹⁰.

Front

What does the term 'orbital' refer to?

Back

An orbital is a region in an atom where there is a high probability of finding an electron.

Front

What is the electron configuration of iodine?

Back

[Kr] 5s² 4d¹⁰ 5p⁵.

Front

What is the Aufbau principle?

Back

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