This subatomic particle orbits the nucleus and carries a negative charge.
Difficulty: EasyThis phenomenon explains why electrons are ejected from metals when light of sufficient frequency shines on them.
Difficulty: MediumThis approximation treats electrons as independent particles moving in an average potential from the nucleus and other electrons.
Difficulty: HardThis positively charged particle resides in the atomic nucleus.
Difficulty: EasyThis quantum number specifies the orientation of an orbital in space and ranges from -l to +l.
Difficulty: MediumThis method combines multiple Slater determinants to account for electron correlation beyond Hartree-Fock.
Difficulty: HardThis neutral particle shares the nucleus with protons.
Difficulty: EasyThis spectral series in hydrogen produces ultraviolet light from transitions to the ground state.
Difficulty: Medium
