Electron Configuration & Groups on the Periodic table

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 is the Aufbau Principle?

Back

A rule stating that electrons occupy the lowest energy orbitals first before filling higher energy orbitals.

Front

What is the maximum number of electrons that can occupy an orbital?

Back

2 electrons, due to the Pauli Exclusion Principle.

Front

What does the term 'sublevel' refer to in electron configuration?

Back

Sublevels are divisions of principal energy levels (n) that contain orbitals, such as s, p, d, and f.

Front

How many orbitals are in the p sublevel?

Back

3 orbitals.

Front

What is the significance of the periodic table groups?

Back

Elements in the same group have similar chemical properties and the same number of valence electrons.

Front

What is shorthand notation in electron configuration?

Back

A simplified way to represent electron configurations using the nearest noble gas to reduce writing.

Front

What is the electron configuration for Magnesium?

Back

1s² 2s² 2p⁶ 3s².

Front

What is the electron configuration for Nickel?

Back

[Ar] 4s² 3d⁸.

Front

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

Back

14 electrons, as there are 7 orbitals in the f sublevel.
