A look at the transition metal unununium, which was renamed roentgenium in 2004. Includes basic information, including symbol, number, mass, melting and boiling points, and numbers of protons, electron, and neutrons.

The experiments of Columbia University physicists (left to right) Chien-shiung Wu (1912-1997), Y.K. Lee, and L.W. Mo confirmed the theory of conservation of vector current. In the experiments, which took several months to complete,...

This is a simple picture of a hydrogen atom using the Bohr model. A negatively charged electron can be seen on the outside of the positively charged proton.

This diagram shows a basic atom structure with an atom core, proton, neutron and electron.
