Calculate the number of valence electrons in Neodymium using its electron configuration step by step.
Determine the number of valence electrons in Neodymium (Nd, Element 60)
The abbreviated (condensed) ground electronic configuration for Neodymium is:
[Xe] 4f4 6s2
Calculate Electronic Configuration for Neodymium
Electrons in atomic orbitals outside the [Xe] core are the outermost electrons:
4f4 6s2
Extract the principle quantum number, n, and number of electrons from the electron configuration:
Electron Configuration | n | Orbital | Number of Electrons |
---|---|---|---|
4f4 | 4 | f | 4 |
6s2 | 6 | s | 2 |
The outermost electrons with the largest principal quantum number (in this case, n = 6) are valence electrons.
Neodymium (Nd) has 2 valence electron(s).
