CH 301 Lecture Notes - Lecture 12: Radial Distribution Function, Atomic Radius, Ion
Document Summary
The idea that we can find electron configuration of any element by building from. Exceptions can occur at places where a subshell can either be completely filled or half filled. Electrons should be placed into separate orbitals before going into the same orbital. Electrons in an atom are layered into shells as we fill up different n levels. The next electron is forced into a higher energy orbital. Electron shielding: the outer most electron is shielded from the full nuclear charge because of the negative charges of the other electrons between it and the nucleus. Effective nuclear charge = nuclear charge - # of core electrons. Ionization energy: energy required to remove an electron from a gas phase. Second ionization energy is the energy required to remove an electron from the 1+ ion. Atomic radii: can be determined based on experimental data. Size of an atom is referred to as its atomic radius.
