Grandpa and Grandpa...

Grandpa and Grandpa were sitting in their porch rockers watching the beautiful sunset and reminiscing about "the good days," when Grandma turned to Grandpa and said, "Honey, do you remember when we first started dating and you used to just casually reach over and take my hand?"

Grandpa looked over at her, smiled and took her aged hand in his. With a wry little smile Grandma pressed a little farther, "Honey, do you remember how after we were engaged you'd sometimes lean over and suddenly kiss me on the cheek?"

Grandpa leaned slowly toward Grandma and gave her a lingering kiss on her wrinkled cheek.

Growing bolder still, Grandma said, "Honey, do you remember how, after we were first married, you'd kind of nibble on my ear?"

Grandpa slowly got up from his rocker and headed into the house. Alarmed, Grandma said, "Honey, where are you going?"

Grandpa replied, "To get my teeth!"

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.«
