In this video, we explore the fundamental question: Why does changing just one proton in the nucleus of an atom create a ...

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 ...

An international research team with a Korean scientist has discovered an inversion phenomenon in 'symmetric nuclei'—where the ...

Protons are particles that exist in the nucleus of all atoms, with their number defining the elements themselves. Protons, however, are not fundamental particles. Rather, they are composite particles ...

The stuff of daily existence is made of atoms, and all those atoms are made of the same three things: electrons, protons and neutrons. Protons and neutrons are very similar particles in most respects.

The proton number (Z) of an atom is the number of protons it contains. All the atoms of a particular element have the same proton number (number of protons). The atoms of different elements have ...

Atomic Number and Mass Number of Elements: Atoms are the building blocks of matter. They are responsible for the format of all living and non-living things. Understanding their molecular structure and ...

Scientists think an asteroid could contain previously unknown elements. Asteroid 33 Polyhymnia appears to be denser than the densest element in the Periodic Table. The densest naturally occurring ...

The heaviest element that humans have ever found is called oganesson. Each atom of the stuff packs a whopping 118 protons into its dense center. In contrast, hydrogen—the most abundant element in the ...

From the first moments of Big Bang to the present day, the cosmic story of how our Universe evolved to become filled with stars, galaxies, and all that we can see and detect is a tale that unites us ...
