Almost Saturday Science Videos and more: Playing with the periodic table

19 Nov

Somehow Facebook, Twitter and my ongoing addiction to NPR have all pointed to fun chemistry science media today. This morning, I was just about to get out of bed when I heard this segment on NPR’s Morning Edition: Planet Money: Why Gold? Planet Money and a Columbia University chemical engineer play bingo with the periodic table to cleverly explain the origin of gold as the metallic basis of wealth.

Then there’s chemistry at a party: a fun little promotional video for science career put together by Marie Curie Actions at the European Commission Research (Hat tip: The Scientist‘s Naturally Selected blog). My favorite segue:  Hydrogen and Neon have  “No Attraction,” but Carbon enters the room to attract four happy Hydrogens. Those poor noble gases are just destined to die alone.

Finally, I picked this up via Facebook: your periodic table tie-in to Harry Potter mania this weekend. Enjoy “The Elements” courtesy of Daniel Radcliffe. Awesome.

Molecule of the Week: Hydrogen

14 Jun

Though hydrogen is the smallest atom and is perched at the top left of the periodic table, hydrogen in nature exists as two atoms hooked together.

Hydrogen hit the news this weekend as a leak led NASA to scrub the Space Shuttle Endeavor launch:

Hydrogen is as clean as chemical fuels get: burning it produces water, a useful waste product. But just like a possible leak of other fuels including gasoline, hydrogen is a potential safety concern.

Hydrogen and helium (its sister element on the right side of the periodic table) form the basis of new stars. These chemicals rotate and condense, ultimately integrating their nuclei to form larger elements through nuclear fusion and releasing energy.
