What is a mole? | The Chemistry Journey | The Virtual School Chemistry help, high school chemistry, college chemistry, chemistry tutorial, chemistry 118 Videos Explaining Each Element In The Periodic Table If you’re a science teacher, you’re going to want to bookmark this as soon as possible. If you’re not a science teacher, heck, you’ll still love this and learn a thing or two. The University of Nottingham has created ‘The Periodic Table of Videos‘ and it’s just what the title would imply. 118 videos that explain each element. Video journalist Brady Haran and working chemists from the University of Nottingham assembled these videos for the world to enjoy. Now, they say they’re going to start improving and beefing up each video with new stories, better samples, and bigger experiments. They also have a new video series, dubbed ‘The Molecular Videos’ which is a showcase of their favorite molecults and compounds.

Halflife The applet lists a "halflife" for each radioactive isotope. What does that mean? The halflife is the amount of time it takes for half of the atoms in a sample to decay. The halflife for a given isotope is always the same ; it doesn't depend on how many atoms you have or on how long they've been sitting around. For example, the applet will tell you that the halflife of beryllium 11 is 13.81 seconds. Let's say you start with, oh, 16 grams of 11Be. Hmmm...so a lot of decays happen really fast when there are lots of atoms, and then things slow down when there aren't so many. That's exactly right. Notice how the decays are fast and furious at the beginning and slow down over time; you can see this both from the color changes in the top window and from the graph. You'll also notice that the pattern of atoms in the top picture is random-looking, and different each time you run the applet, but the graph below always has the same shape.

There are so many elements – and more getting added all the time — and only a couple of letters to tell them apart, making it difficult to tell your Copernicium (Symbol: Cn) from your Cerium (Symbol: Ce). Thanks to a book by Japanese artist Benpei Yorifuji, there’s now a much easier way to identify the elements: Check out their hair and fashion sense. In Wonderful Life With the Elements: The Periodic Table Personified, Yorifuji makes the many elements seem a little more individual by illustrating each one as as an anthropomorphic cartoon character, with distinctive hairstyles and clothes to help readers tell them apart. Nitrogens have mohawks because they “hate normal,” for example, while noble gases have afros because they are “too cool” to react to extreme heat or cold. Man-made elements are depicted in robot suits, while elements used in industrial application wear business attire.
