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

Valence Electrons in Hydrogen

Determine the number of valence electrons in Hydrogen (H, Element 1)

Step 1: Look up the electronic configuration for Hydrogen

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


Calculate Electronic Configuration for Hydrogen

Step 2: Identify the outermost electrons using the electronic configuration

Electrons in all the atomic orbitals are the outermost electrons:


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 = 1) are valence electrons.


Hydrogen (H) has 1 valence electron(s).
