The ground state electron configuration of an atom is a representation of an atom showing the electrons in the occupied orbitals of the atom. The ground state configuration is determining by adding electrons to available orbitals so as to obtain the lowest total energy Pauli exclusion principle an orbital can hold at most two electrons and then only if the electrons have opposite spin Aufbav Principle electrons are added to the orbitals of subshells in a specific order. This order typically corresponds to the increasing energy of the subshell. 1s 2s 29 3s 3p 4s 3d 4p 5s 4d 5p 6s 4f 5d 6p 7s 5f…. . Hund’s Rule states that the lowest energy arrangement of electrons in a subshell is obtained by putting electrons into separate orbitals of a subshell with the same spin before pairing.

Unformatted text preview: Vanadium 23 [Ar] 3d 3 4s 2 Paramagnetic: has unpaired electrons and is attracted to a magnet Diamagnetic: has no unpaired electrons and NOT attracted to a magnet d N3- diamagnetic; Ca2+ diamagnetic; Co2+ paramagnetic Atomic Radius: decreases across the table and up the table Ionic Radius: cations are small then parents; anions are larger then parents -Same trend as atomic radius: decrease up and across table Ionization Energy: energy needed to remove atom in gas phase-Increase as you go up and across table Electron Affinity: energy change when an electron is attached to an atom in the gas phase (negative value)-Increases across the table (more negative) and decreases down the table...
