November 11 – Science Discovery Announced – on a Kids' TV Show???

November 11 - Science Discovery Announced - on a Kids' TV Show???


When new chemical elements are discovered, there is normally some excitement and certainly worldwide announcements. But all of that was delayed when the heavy elements americium and curium were discovered. Why? Because of a little thing called World War II.

Scientists working at University of California, Berkeley, produced these radioactive metals while working with the Manhattan Project. This top-secret project was an attempt to understand and control the process of nuclear fission—that is, an attempt to split atoms and to create a horrible new weapon, the atomic bomb.

(By the way, the main site of the Manhattan Project was Los Alamos, New Mexico—an entire town that was kept secret during the war. I just went there and visited historical and scientific museums. Very interesting!)

Because of the secrecy of the Manhattan Project, the two new elements could not be revealed until after the war. It was planned that they would be officially unveiled at a meeting of the American Chemical Society, but five days before that (November 11, 1945), head scientist Glenn Seaborg was being interviewed by children for a special episode of a radio show for kids. The show was called Quiz Kids, and I am not sure what the child interviewing Seaborg asked, but the scientist ended up telling all the children listening about the two new elements!

Wow!

This is the only known time when a scientific announcement has been made on a kids’ entertainment show.

What do you think curium and americium are named for?






ANSWERS: Curium is named for the scientists Marie and Pierre Curie, who discovered radium and worked on radioactivity. It is the first element to be named for a historical person. Americium is named for America, the continent on which the element was first created. This name is an analogy to europium (named for Europe in the early 1900s). Later elements made by U.C. Berkeley scientists include californium and berkelium.


Atomic Numbers

The higher an element’s atomic number, the larger and heavier that element’s atoms are.

The lightest element is hydrogen. Most hydrogen atoms have only one proton and one electron. The atomic number of an element is the number of protons it has, so hydrogen’s atomic number is 1.

Americium is atomic number 95. It has 95 times more protons than hydrogen does! Plus, each atom is a LOT heavier, because it has around 148 neutrons, too!

Curium is atomic number 96. The average curium atoms has 151 neutrons.


Both of these elements are considered unstable. Without any outside help, they break down into smaller elements, releasing radiation. This is what we mean when we say that these elements are radioactive.

  • Play a very element-ary game! 
  • Watch videos about the elements (including today’s stars, Am and Cm). 

(By the way!)

I originally posted that the anniversary of the scientific discovery on Quiz Kids occurred on November 6. Apparently that was an error! That show was taped on 11/11/1945. Sorry about that!
