56 First ionization Energy plot (Energy versus atomic number) 57 58 59 Ionization Energies 1st I.E. 2nd I.E. p3→p4 + + Overall trend of increasing I.E. from left to right is evident, but major exceptions in the second I.E. 60 Atomic Radii 1. Single – bond covalent radius (rcov) of an element. Used in bond length determination. van der waals radius (rvdw) non-bonded distance of two atoms that are touching one another. ionic radius (rion) Radius used in ionic compounds these have been tabulated and are additive. 2. 3. Page 61, Table 2-15 Na+ 1.16 Å (116 pm) Cl- 1.67 Å (167 pm) Therefore NaCl internuclear separation is 2.83 Å 61 62 Atomic Radii & van der Waals radii 1. Alkali metals are largest 2. Halogens (noble gases) are smallest Why? (page 62. Effective nuclear charge increases but electrons in the orbitals added to the same level, n, are progressively less shielded from the increasing positive charge of the nucleus from each added proton) Ionic Radii 1. Alkali metals beco...
