1.8 Valence Electrons and Ionic Compounds
1.5 Atomic Structure and Electron Configuration
The complete ground-state electron configuration of a neutral germanium atom (
\(\text{Ge}\)) is \(1s^2\,2s^2\,2p^6\,3s^2\,3p^6\,3d^{10}\,4s^2\,4p^2\). Which of the following statements best identifies the number of valence electrons in a \(\text{Ge}\) atom and provides the correct justification for why the \(3d^{10}\) electrons are classified as core electrons?
