Electrons are arranged as shells  subshells  orbitals 3d 4s 3p 3s Degenerate orbitals 2p -same energy 2s 1s energy Aufbow Principle – lower energy orbitals fill first Hund’s Rule – degenerate orbitals are filled halfway before pairs occur 2p orbital Electrons in the new orbital Total electrons s orbitals  2 electrons 2 p orbitals  6 electrons 8 d orbitals  10 electrons 18 f orbitals  14 electrons 32 3 types of notation 1) Orbital Box Diagram 2) spdf notation 3) Noble gas notation Notation Hydrogen(1) Helium(2) Lithium (4) Sulfur (16) Orbital box diagram 1s 1s 1s 2s 1s 2s 2p 3s 3p pp pp pp 1 2 2 1 2 2 6 2 4 spdf notation 1s 1s 1s 2s 1s 2s 2p 3s 3p Noble gas [He] 2s 1 [Ne] 3s2 3p 4 Half filled and completely filled orbitals are the most stable 2p Half filled 2p completely filled Z* - ZeffEffective Nuclear Charge = [Z – (number of inner electrons)] – it is the net charge experienced by a particular electron in a multi-electron atom resulting from a balance of the attractive forces of the nucleus and the repulsive forces of other electrons - Z* increases across a period 2 1 1 - For Li 1s 2s Z* ≈ 3-2≈1 for the electron in 2s Atomic Radium – half the diameter of an atom and half the distance between nuclei in a diatomic molecule. – largest in the LEFT BOTTOM of the periodic table Size and charge Nuclear charge and ionization energy decrease, size increase increase, Forces pull toward nucleus ionization energy decrease higer Zeffans that electrons hold on more tightly to the nucleus (i.e. There are stronger forces holding them together) smaller + Li Li 3+ and 3- 3+ and 2- |???????????????????????????????? ????ℎ???????????????? | |???????????????????????????????? ????ℎ???????????????? | Higer proportion of positive charges to negative charges will result in a larger number and a smaller atom when considering an atom and its ions Ex. |3| 3 | |2|= 1.5 > 1 = 3 | (IE) ionization energy – minimum energy required to remove an electron from the ground state of a gaseous atom
