Since the atomic nucleus was first proposed in 1911, physicists simply assumed it was round. But are the nuclei of atoms really round? Intuitively this shape makes sense and physicists believed it ...

What do atoms look like? This is actually an impossible question to answer: Atoms are so tiny that we can't see them using light, even looking through the most powerful lenses and microscopes. The ...

Static electricity works because electrons are strongly attracted to protons, right? But, in atoms, electrons are right there, next to the protons in the nucleus. Why don’t the electrons zip directly ...

Atoms are very small. They have a radius of around 1 × 10 10 metres. This symbol shows that chlorine has 35 particles in the nucleus (protons and neutrons), 17 of which are protons. It also tells us ...

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.

No one really knows what happens inside an atom. But two competing groups of scientists think they've figured it out. And both are racing to prove that their own vision is correct. Here's what we know ...
