In 2013, physicists used a "quantum microscope" to peer inside a hydrogen atom. Credit: A. S. Stodolna et al., 2013 ...

An atom consists of a heavy center, called the nucleus, made of particles called protons and neutrons. An atom has lighter ...

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

You could swim through the deepest voids and encounter a single hydrogen atom in an entire football field's worth of space.

Explain to students that the two electrons in the bond between the hydrogen atom and the oxygen atom can be thought of as “belonging” to each atom. This gives each hydrogen atom two electrons in its ...

Hydrogen Binding Energy Is Insufficient for Describing Hydrogen Evolution on Single‐Atom Catalysts. Angewandte Chemie International Edition , 2025; DOI: 10.1002/anie.202425402 Cite This Page : ...

Explain to students that in a hydrogen atom, the negatively charged electron is attracted to the positively charged proton. This attraction is what holds the atom together. Tell students that hydrogen ...

The hydrogen atom — one proton, one electron — loves to hook up with other elements. Hydrogen is an ingredient in molecular matter including methane, vegetable fats salt water, ...

Like ordinary water—H 2 0—each molecule of heavy water contains two hydrogen atoms and one oxygen atom. The difference, though, lies in the hydrogen atoms.

Greene “with that beautiful blonde hair is driving down the highway in a hydrogen car,” he said. “And the problem with a hydrogen car, if something goes wrong, it’s like the atom bomb went ...
