Atoms are made up of a nucleus, protons and electrons. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works. Atoms are the basic units of matter.

An atom is the smallest unit of an element that retains its chemical properties. It is made of protons, neutrons, and electrons. (Image: M ...

Since the beginning of time, human beings have sought to understand what the universe and everything within it is made up of. And while ancient magi and philosophers conceived of a world composed of ...

A team of physicists say they have created the first coherent picture of atomic nuclei from their composite particles, quarks and gluons. The 20th century was a pretty busy hundred years for particle ...

Figure 1: Electron flux as a function of longitude in different L shells for the period 4–14 January 2013. Figure 2: Dependence of an electron’s drift path on its altitude and L shell. Figure 3: ...

Physicists have known for decades that particles called gluons keep protons and neutrons intact—and thereby hold the universe together. Yet the details of how gluons function remain surprisingly ...

Inside the nucleus of some atoms, protons appear to be doing very unexpected things. They are pairing up far more often than usual when they get extremely close to each other, and physicists don’t ...
