Electron Configuration Practice

Front

What is electron configuration?

Back

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

Front

What does the notation '1s2 2s2 2p6' represent?

Back

This notation represents the electron configuration of an atom, showing the number of electrons in each subshell.

Front

How many electrons can the 's' subshell hold?

Back

The 's' subshell can hold a maximum of 2 electrons.

Front

How many electrons can the 'p' subshell hold?

Back

The 'p' subshell can hold a maximum of 6 electrons.

Front

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

Back

The third energy level can hold a maximum of 18 electrons (2 in 's', 6 in 'p', and 10 in 'd').

What is the electron configuration for Neon (Ne)?

Back

1s2 2s2 2p6

Front

What is the electron configuration for Phosphorus (P)?

Back

1s2 2s2 2p6 3s2 3p3

Front

What element has the electron configuration '1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5'?

Back

Bromine (Br) has this electron configuration.

Front

What is the significance of the Aufbau principle in electron configuration?

Back

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

Front

What is Hund's rule?

Back

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