Cesium is not only a cool looking silvery-gold alkali metal element that is liquid at room temperature, but it is also used in atomic clocks. These clocks measure frequency with an accuracy of 2 nanoseconds per day, or one second in 1.4 million years, which means they would be off by about 2 seconds since the extinction of the dinosaurs 65 million years ago. Pretty cool application of an extremely pyrophoric element if you ask me. Check out the video of a volatile reaction between water and Cesium below.

ReplyDeleteI don't even like chemistry that much, but you still managed to keep me entertained.
ReplyDeleteYeah, it's stuff that I just don't have the mind for, but it's still interesting.
ReplyDeleteThat old guys fro was very distracting. Good video and that's a very interesting fact about atomic clocks
