Valence Electrons in Neon (Ne)

Calculate the number of valence electrons in Neon using its electron configuration step by step.

Enter the atomic number or symbol of any element, and this calculator will calculate its valence electrons with steps.

Valence Electrons in Neon

Determine the number of valence electrons in Neon (Ne, Element 10)

Step 1: Look up the electronic configuration for Neon

The abbreviated (condensed) ground electronic configuration for Neon is:

[He] 2s2 2p6

Calculate Electronic Configuration for Neon

Step 2: Identify the outermost electrons using the electronic configuration

Electrons in atomic orbitals outside the [He] core are the outermost electrons:

2s2 2p6

Step 3: Use the principle quantum number to identify the valence electrons

Extract the principle quantum number, n, and number of electrons from the electron configuration:

Electron ConfigurationnOrbitalNumber of Electrons

The outermost electrons with the largest principal quantum number (in this case, n = 2) are valence electrons.


Neon (Ne) has 8 (2 + 6) valence electrons.
