Scientists at ORNL used neutrons to see hydrogen atoms, flashing in green, ending a decades-long debate about an enzyme that could target aggressive cancers through inhibitor design. Disclaimer ...

Based on accepted cosmological models, hydrogen and helium were the only elements in the earl. These coalesced to form the ...

Even small movements of hydrogen, shown in yellow, were found to cause large energy shifts in the attached iron atoms, shown in silver, which could be of interest in creating novel chemical reactions.

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.

"There are only a few viable yet rare scenarios in the cosmos where these elements can form, and all such locations need a copious amount of neutrons." Free neutrons have a half-life of only 15 ...

Understanding the origin of heavy elements on the periodic table is one of the most challenging open problems in all of ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...
