Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons" (particles present in atomic nuclei). Positron An elementary particle having the same mass and magnitude of charge as an electron but exhibiting a positive charge; the antiparticle...
Protons and Neutrons: What Are They?Jean Louis Van Belle
Everything is made up of atoms. So, what makes up atoms? Atoms are made of protons, neutrons, and electrons, which are also called subatomic particles. Protons and neutrons are in the nucleus of the atom, while electrons are located in orbitals that surround the nucleus. ...

An atom has three types of very tiny particles called protons, neutrons and electrons. The center of an atom is called the nucleus, and it is made up of protons and neutrons. The electrons in an atom fly around and above the nucleus in a cloud-like formation. The protons have a positiv...
Protons are subatomic particles that, along with neutrons, comprise the nucleus or central portion of an atom. The rest of the atom consists of electrons that orbit the nucleus, much as Earth orbits the sun. Protons can also exist outside an atom, in the atmosphere or in space. ...
ICSEC - Grade 09 - CHEMISTRY - Atomic Structure And Chemical Bonding - Q23
It is now generally accepted that atoms are made up of three particles called neutrons, protons, and electrons. The neutrons and protons are found in the nucleus (center) of the atom and the electrons reside in a shell surrounding the nucleus. Neutrons are heavy particles, but they have no...
light). Such 'ballistic' protons have led to many interesting discoveries in particle physics / chemistry. One reason why protons are so important for such research is that, unlike neutrons, protons are stableoutside of an atomic nucleus, which makes it possible to use them in certain ...
Continuing use of sodium as an example, what makes a sodium atom, a sodium atom ? Could another type of atom just happen to have 11 protons, 11 electrons and 12 neutrons ? No. The number of protons = the 'Atomic Number', which is sometimes referred to as 'Z', defines the type ...
