    Scientists confirm new element after atoms collide New Element #115 has been announced but is not officially "approved" (which must happen before it is added to the official periodic table.) Scientists "slammed calcium atoms into americium." Then, the element vanished quickly into a flash of radiation - but scientists could measure it. It has 115 protons at its center so that puts it at 115 on the table. This would be a great one for classes to discuss in chemistry. Neat topic.

    A scale model of a hydrogen atom where the electron is made as big as 1 pixel. Does a great job of showing how much empty space matter is really made up of.
