The “lead” of a pencil is actually made of a substance called graphite which is made of carbon atoms. The picture shows a close-up of one carbon atom. A hydrogen atom has one proton as the nucleus and ...

The film report discusses the nature of electricity, explaining its significance in daily life and its presence in various ...

The sample can be of any kind, it could be liquid, solid, or even gas. The sample will be affected by the magnetic field as long as it contains either protons, neutrons, or electrons, or any ...

Atoms are in fact made up of three smaller particles called protons, electrons and neutrons. The protons and neutrons are contained in the nucleus, the tiny centre of an atom, with smaller ...

The question of what protons or neutrons are made up of has an apparently simple answer: quarks and gluons. However, when it comes to atoms’ third component, electrons, the answer is not as easy.

To get to grips with it, it helps to first understand that atoms, the basic units of all matter, are made of protons, neutrons and electrons. It is the number of protons, otherwise known as the ...

Protons have a charge of +1. Electrons have a charge of -1. Neutrons are neutral, as its name implies. A stable atom has a net charge of 0. In other words, it has an equal number of protons and ...

In the case of lead-208—the heaviest stable isotope known so far—a team of researchers led by physicist Jack Henderson ...

When two hydrogen atoms and an oxygen atom get close enough, the electron from each atom feels an attraction from the protons in the other atom's nucleus. This attraction pulls the atoms together. The ...

The visible universe—including Earth, the sun, other stars, and galaxies—is made of protons, neutrons, and electrons bundled together into atoms. Perhaps one of the most surprising discoveries ...
