The word magic is not often used in the context of science. But in the early 1930s, scientists discovered that some atomic ...

The film discusses the dual nature of atomic energy, likening it to the sun, which can both sustain and destroy life. It explains the structure of atoms and the process of nuclear fission, leading ...

Through these activities, students will be introduced to some of the characteristics of electrons, protons, and neutrons, which make up atoms. Objective Students will be able to explain, in terms of ...

All the oxygen in your body is thanks to magic numbers of protons and neutrons in the nucleus.

The question of where atoms come from requires a lot of physics to be answered completely – and even then, physicists only have good guesses to explain how some atoms are formed.

Now, most of the atoms in the universe are the two simplest kinds: hydrogen, which has one proton, zero neutrons and one electron; and helium, which has two protons, two neutrons and two electrons.

Many heavy atoms form from a supernova explosion, the remnants of which are shown in this image. NASA/ESA/Hubble Heritage ...

Atoms of different elements have different numbers of protons, neutrons and electrons. For example, a hydrogen atom has one proton, one electron and zero neutrons, while uranium has 92 protons, 92 ...

Now, most of the atoms in the universe are the two simplest kinds: hydrogen, which has one proton, zero neutrons and one electron; and helium, which has two protons, two neutrons and two electrons.

Richard Feynman, a famous theoretical physicist who won the Nobel Prize, said that if he could pass on only one piece of ...
