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 ...

Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom has a net charge of 0. In other words, it has an equal number of protons and ...

NASA’s oldest active astronaut just gave Earth a jaw-dropping look at one of the planet’s rarest and most beautiful phenomena ...

Physicists use the Relativistic Heavy Ion Collider (RHIC) to test key accelerator strategies for the cutting-edge ...

When two hydrogen atoms and an oxygen atom get close enough, the electron from each atom feels an attraction from the protons in the other atom's nucleus. This attraction pulls the atoms together. The ...

The atom is a complex system of particles. It's made up of a central nucleus consisting of protons and neutrons, called nucleons, with electrons orbiting around the nucleus. Nobel prize-winning ...

The research is published in the journal Nature Chemistry. There are two possible mechanisms here: Either electrons and protons are transferred simultaneously ("concerted"), or the transfer occurs ...

So why do so many life-forms breathe oxygen? There are probably thousands of kinds of metabolisms, or chemical processes that ...

The NASA/ESA Solar Orbiter recently recorded the highest-ever concentration of a rare helium isotope (3He) emitted from the Sun. A Southwest Research Institute-led team of scientists sought the source ...
