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 ...

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 ...

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 ...

For atoms, bonding involves a give, take and sharing of electrons. For more than 100 years, scientists thought that eight electrons was the limit of a single atom’s generosity. But now it’s nine. By ...

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 ...

A novel experiment has revealed a phenomenon called the Bohr–Weisskopf effect in a pear-shaped nucleus in a molecule for the first time.
