Document Summary

The solution to schr dinger"s equation for the h atom reveals that electrons having a particular energy reside in a corresponding atomic. Orbital represented by the quantum numbers n, l, ml (we will revisit ms i ch. In the process, it"s electron transfers to an orbital that is larger and less. Stable : how do we measure the stability of an orbital, photoelectron spectroscopy. #1: stability of orbitals increases as nuclear charge increases > Ionization energy is minimum energy require to remove= one electron from an atom in it"s ground state ionization energy increases from left to right (across a period) ionization energy increases going up a period. The higher the nuclear charge, the stronger the binding of electrons in a given orbital: e ect of nucleus. It is more di cult to remove an electron from a positive species. The electrons closer to the nucleus screen the electrons that are further away: electrons are primarily screened by inner electrons.
