Far lighter than other ions collided at the LHC, oxygen (and neon) could tell us about conditions in the early universe.

What happens when the smallest building blocks of matter refuse to play by the rules of traditional physics? For decades, ...

The invisible dark matter is one of the universe's biggest mysteries, and its existence is confirmed only by the ...

Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...

The International Atomic Energy Agency (IAEA) has reported that Iran has already enriched a large amount of uranium up to 60%.

A proton’s mass number represents how many protons and neutrons atoms of this type have. The mass number of Carbon-12 is 12; it has six protons and six neutrons. The mass number of Carbon-14 is 14; it ...

The number of protons is what defines the element. Oxygen, for example, has eight protons. However, the number of neutrons in an atom can vary, leading to different forms of elements, called isotopes.

The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic nuclei — the center part of atoms, which make up all matter — were more ...
