The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and one electron in the region outside the nucleus. The electron and proton are attracted to each other.

When two hydrogen atoms get close enough, the electron from each atom feels an attraction from the proton in the other atom's nucleus. This attraction pulls the atoms together. The electrons end up ...

It also tells us that chlorine has 18 neutrons (35 - 17) and, as the number of electrons and protons are equal in a neutral atom, chlorine also has 17 electrons. The relative mass of a nucleus is ...

Chadwick's own research focused on radioactivity. In 1919 Rutherford had discovered the proton, a positively charged particle within the atom's nucleus. But they and other researchers were finding ...

In a groundbreaking discovery, scientists have revealed an unprecedented map of the forces acting within a proton. This map ...

But materials that can efficiently conduct protons—the nucleus of the hydrogen atom—could be key to a number of important technologies for combating global climate change. Most proton ...

Since a nucleus contains protons and neutrons, most of the mass of an atom is concentrated in its nucleus.

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton's inner ...

The difference, though, lies in the hydrogen atoms. In ordinary water, each hydrogen atom has just a single proton in its nucleus. In heavy water, each hydrogen atom is indeed heavier, with a ...

The Proton builds on the Wattbike Atom, a model marketed towards the ardent cyclist and the more appropriate option for keen road cyclists. I’m a bit taken aback by the simplicity of the Proton.

Two experiment collaborations, the g2p and EG4 collaborations, combined their complementary data on the proton’s inner ...
