41. The kinetic energy of the bombarding electrons should have higher energy than the ionization energy of the sample molecule. 42. The atomic analog to nuclear magic numbers are those numbers of electrons leading to discontinuities in the ionization energy . 43. Alt = A graph of ionization energy vs . atomic number showing sharp peaks for the noble gas atoms. 44. Electronegativity increases in the same manner as ionization energy because of the pull exerted on the electrons by the nucleus. 45. This causes the first ionization energies of the 7d transition metals to be smaller than those of their lighter congeners. 46. Its first ionization energy should be about 395.6 kJ / mol and its metallic radius should be about 170 picometers. 47. It takes a bit of energy, the ionization energy of oxygen is pretty high ( 1164 kJ / mol ). 48. Electron binding energy : A generic term for the ionization energy that can be used for species with any charge state. 49. This decrease in atomic radius also causes the ionization energy to increase when moving from left to right across a period. 50. Because of its low ionization energy , W 2 ( hpp ) 4 is easily oxidized back to the dichloride by dichloromethane.
