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 ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Protons and neutrons are the heaviest particles in an atom and as a result they make up most of its mass. The mass of electrons is ...

Nuclear energy is a form of energy released from the nucleus, the core of atoms, made up of protons and neutrons. This source of energy can be produced in two ways: fission – when nuclei of atoms ...

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 ...

If you expanded an atom to the size of a baseball, what would it look like? And how would the inside look if you sliced it open? The nucleus is the atom’s central core and contains more than 99.9 ...

Part of Physics (Single Science) Unit 1: Atomic and nuclear physics Most of the mass and all of the positive charge of an atom is in the nucleus. Most of an atom is empty space, (a vacuum). In 1897, ...

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.

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 ...

MIT scientists used radium monofluoride atom to observe electrons entering atomic nuclei, revealing new details of nuclear magnetism.
