我猜测最有可能的原因可能是d层和f层和s,p层能级相差太多、e.g. 3d和4s的能级就相差不多、而根据传统定义、只有最外层的才能算valence electrons、所以3d就被排除掉了（虽然这种定义对于解释transition metal的化学性质基本没帮助）、而你的选项valence electrons are all outermost electrons in "a su...

How many valence (outer-shell) electrons does each of the following atoms have? (a) Oxygen (b) Magnesium (c) Fluorine Valence Electrons: Valence electrons are the outermost electrons of an element or an ion. These are the electrons that are most ...
electrons. However, the total signal of the rescattered electrons modulates in time with approximately the same contrast as the total signal. We thus conclude that the electronic dynamics in NO causes a variation of the rescattering probability, but it hardly affects the shape of the photoelectron...
carefully so you understand how electrons are added to the subshell of lowest energy until it reaches its capacity; then the subshell of the next energy level begins to be filled. The electrons in the highest numbered subshells are thevalenceelectrons, which comprise the valence shell of the ...
What are valence shell electrons?Subatomic Particles:Atoms are the tiny building blocks that make up all matter that exists. Atoms have within them subatomic particles called protons, neutrons and electrons. Protons and neutrons exist inside the nucleus of the atom, while electrons orbit the nucleus...
