protons electrons stock videos & royalty-free footage A helium atom consists of two protons, two neutrons, and two electrons. It's the second-lightest and simplest element in the periodic table, and ...

The size of an atom is only a few angstroms at most - there are 10 billion angstroms in 1 metre. This video also looks at the ...

A physicist explains how atoms arrange themselves into molecules – and how scientists are able to image these tiny bits of ...

Each particle has its own charge and its own mass.

For example, baryons, such as protons and neutrons, are combinations of three quarks bound tightly together by strong force-carrying gluons. When individual quarks are ripped from hadrons ...

There are striking similarities between how elementary particles come together to form atoms, molecules and eventually ...

"With evidence that quarks and gluons are entangled, this picture has changed. We have a much more complicated, dynamic system." ...

While particle physicists have made significant progress in understanding the inner structures of protons, neutrons, and other hadrons, there is still much to learn. Quantum chromodynamics (QCD) says ...

Using the MeerKAT telescope in South Africa, an international team of astronomers has detected 26 new Galactic radio transients. Most of them turned out to be rotating radio transients (RRATs ...

They keep on passing through your tissues and eventually exit the body. That’s why they can often damage healthy cells along with the cancer cells. Protons are positively charged particles found in ...
