Problem: How many valence electrons does Cu have?

FREE Expert Solution

We have to determine the number of valence electrons in a copper atom.

The number of valence electrons can be determined by writing the electron configuration.

We can look up the periodic table for the atomic number of Cu. Z = 29.

Electronic configuration is written in a way that electrons fill the orbitals with lower energies first before filling orbitals with higher energies.

The sequence of orbitals for electron configuration can be seen from this diagram.
