| 41. | Sulfur trifluoride is not a stable molecule : it has an unpaired electron and is thus a radical.
|
| 42. | ESR dating measures the amount of unpaired electrons in crystalline structures that were previously exposed to natural radiation.
|
| 43. | The molecule is excited with near infrared radiation to the singlet state ( with no unpaired electrons ).
|
| 44. | Triplet carbenes have two unpaired electrons.
|
| 45. | Each Cu 2 + ion has a d 9 electronic configuration, and so should have one unpaired electron.
|
| 46. | If the only consideration were the presense of unpaired electrons, dioxygen would have all of its electrons paired.
|
| 47. | It contains no unpaired electrons and reacts readily with water disproportionating to give Cd metal and Cd 2 +.
|
| 48. | However to imagine that the unpaired electron is somehow confined to the a p orbitals is of dubious merit.
|
| 49. | Isolation of R gives the distance from the origin ( localized unpaired electron ) to the spin active nucleus.
|
| 50. | Damage occurs when the free radical encounters another molecule and seeks to find another electron to pair its unpaired electron.
