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

Valence Electrons in Niobium

Determine the number of valence electrons in Niobium (Nb, Element 41)

Step 1: Look up the electronic configuration for Niobium

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

[Kr] 4d4 5s1

Calculate Electronic Configuration for Niobium

Step 2: Identify the outermost electrons using the electronic configuration

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

4d4 5s1

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 = 5) are valence electrons.


Niobium (Nb) has 1 valence electron(s).
