Calculate the number of valence electrons in Copper using its electron configuration step by step.
Determine the number of valence electrons in Copper (Cu, Element 29)
The abbreviated (condensed) ground electronic configuration for Copper is:
Calculate Electronic Configuration for Copper
Electrons in all the atomic orbitals are the outermost electrons:
Extract the principle quantum number, n, and number of electrons from the electron configuration:
Electron Configuration | n | Orbital | Number of Electrons |
---|
The outermost electrons with the largest principal quantum number (in this case, n = 0) are valence electrons.
Copper (Cu) has 0 valence electron(s).
