In this video, we explore the fundamental question: Why does changing just one proton in the nucleus of an atom create a different element? The number of protons in an atomic nucleus determines the ...

DEEP in the heart of every atom lurk protons, tiny particles from which the chemical elements were forged, first in the searing heat of the big bang and then in the nuclear furnaces of stars. The ...

Through mass measurements of silicon-22 combined with theoretical calculations, researchers have revealed that silicon-22 possesses a double-magic structure similar to that of oxygen-22, while also ...

Physicists working with molybdenum-84, a nucleus containing exactly 42 protons and 42 neutrons, have found that this seemingly balanced atom defies one of nuclear physics’ longest-standing ...

When most of us picture an atom, we think about a small nucleus made of protons and neutrons orbited by one or more electrons. We view these electrons as point-like while rapidly orbiting the nucleus.
