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 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 ...

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 ...

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 ...

The atom is a complex system of particles. It’s made up of a central nucleus consisting of protons and neutrons, called ...

To build other atoms, just add protons, neutrons, and electrons. By the way, you'll need to create each proton and neutron from scratch, using two types of quarks—up quarks and down quarks.

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 ...

This module provides information about the following topics: The Bohr Model of the atom consists of a central nucleus composed of neutrons and protons surrounded by a number of orbital electrons equal ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...
