The telluric screw plotted the atomic weights of the elements on the outside of a cylinder, so that one complete turn corresponded to an atomic weight increase of 16. As the diagram shows, this ...

Founded by scientists and engineers of the Manhattan Project in the wake of the atomic bombings of Hiroshima and Nagasaki, the Bulletin of the Atomic Scientists has been alerting humanity to the ...

The atomic nucleus is made up of protons and neutrons, particles that exist through the interaction of quarks bonded by gluons. It would seem, therefore, that it should not be difficult to ...

For example, the atomic number of chlorine is 17. Every chlorine atom has 17 protons and 17 electrons. It has 17 positive charges and 17 negative charges, meaning that it is neutral overall.

Single photoionisation can align an atomic electron cloud, yet it is unexplored how the alignment evolves during sequential multi-photon multiple ionisation induced by intense X-ray pulses.

The Atomic Mass Data Center and its electronic bulletin are tools for the exchange of information on experimental masses, evaluation of masses, extrapolation of masses, and theoretical masses. One of ...

These must report preliminary research findings that are highly original, of immediate interest and are likely to have a high impact on the analytical spectroscopy community. Communications are given ...

The Nobel Peace Prize was awarded Friday to Nihon Hidankyo, a Japanese organization of survivors of the U.S. atomic bombings of Hiroshima and Nagasaki, for its activism against nuclear weapons.
