Mike Lawrence: Child of Divorce

I really hate the way I found out about my parents divorce. What happened was, my mom took me out for ice cream, and she sat me down, she said, Michael, Im leaving your father, Im going off to marry another man, and Im pregnant. And that was really messed up, cause that should have been three different trips to get ice cream.

First xenon compound

In 1962, the first compound of any “inert gas” was made by Neil Barlett by reacting platinum hexafluorideand xenon to form XePtF6, a yellow-orange solid that was stable at room temperature. The previous autumn, he had prepared a remarkable compound of oxygen with platinum hexafluoride. In that compound, [O2]+[PtF6]–, the platinum hexafluoride, PtF6 was such an extreme oxidizer that the oxygen formed a positive cation. Interestingly, the energy to remove an electron from oxygen (12.2 eV), he realized, was extremely close to that for xenon (12.13 eV). This suggested a xenon compound could be made in a similar way. His success ended the half-century belief that xenon was an inert gas, and is since known as a “noble” gas.«
