The surface of s-orbital electron and d-orbital electrons of atom plays a key role in the hydrogen dissociation on the metals surface.
Table 2 shows the first five s-orbital shells filled (to 5[s.sup.1]) plotted against the Ln(Z) where Z is the associated atomic number for the valid s1 shell.
Z: Shell 1: [1s.sup.1] 3: [2s.sup.1] 5: [2p.sup.1] 11: [3s.sup.1] 13: [3p.sup.1] 19: [4s.sup.1] 31: [4p.sup.1] 37: [5s.sup.1] 41: [Kr].[4d.sup.4].[5s.sup.1] (repeat) 43: [Kr].[4d.sup.6].[5s.sup.1] (repeat) 47: [Kr].[4d.sup.10].[5s.sup.1] (repeat) 57: [5d.sup.1] 71: [5d.sup.1] (repeat) 87: [7s.sup.1] 89: [6d.sup.1] 91: [15f.sup.1] 103: [7p.sup.1] Table 2: Ln (Z) for first s-orbital electron vs.
