Students calculate wavelength, frequency, or the velocity of a wave. Atomic Theory: Electrons on the Atom Bohr’s model of the atom are described. Students calculate wavelength, frequency, or the ...

When physicists search for new semiconductors for chips or lasers, they have been able to rely on sophisticated computer programs - until now. However, it is possible that the models these programs ...

The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

Scientists have developed a new method that can help them probe inside atom’s nucleus. Developed by researchers at MIT, the method uses the atom’s own electrons as “messengers” within a molecule to ...

Stockholm — Three scientists won the Nobel Prize in physics on Tuesday for studying how electrons zip around atoms in fractions of seconds, a field that could one day lead to better electronics or ...
