The standard model of particle physics represents the most comprehensive theory about fundamental or subatomic particles and forces in the universe. The model describes how matter and antimatter ...

Metals, as most know them, are good conductors of electricity. That's because the countless electrons in a metal like gold or ...

Scientists are diving into the deep sea to study one of the universe’s biggest mysteries—quantum gravity. Using KM3NeT, a ...

Dark matter could be an entire dark sector of the universe, with its own particles and forces H ave you ever stood by the sea ...

When building an atom, pay close attention to the particles' electrical charges. Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable ...

An atom is so small that a single drop of water contains more than a billion atoms. Although tiny, atoms are mostly empty space. The simplified model of the atom is that of a cloud of negative ...

Everyday things that we take for granted, things like cause-and-effect and elementary classical laws do not work in the world inside the atom. Particles popping in and out of existence are the ...

This symbol shows that chlorine has 35 particles in the nucleus (protons ... as the number of electrons and protons are equal in a neutral atom, chlorine also has 17 electrons.

A team of researchers from the University of Ottawa has made significant strides in understanding the ionization of atoms and ...

He concluded that all matter was made of tiny particles called atoms. He suggested that an atom was a tiny solid ball. He published his ideas in 1803. This atomic model has changed over time.
