Collectively, protons and neutrons are called nucleons. Along with electrons, they make up the three subatomic particles in an atom.

An atom of oxygen contains eight neutrons. A neutron is one of the particles that make up matter, which is any substance that takes up space. Neutrons are fundamental particles, meaning that they cannot be broken down.

The most abundant isotope of magnesium has 12 neutrons; it is therefore, technically known as magnesium-24. Calculating the number of neutrons in an isotope of any element involves subtracting that element's atomic number from its atomic weight. Magnesium's number is 12, and its weight is just over

There are 20 neutrons in potassium. An atom contains neutrons, protons and electrons, and there are 19 protons and 19 electrons in potassium. Neutrons have no electrical charge, while protons have a positive charge and electrons have a negative charge.

James Chadwick discovered neutrons in 1932, PBS states. Neutrons are the particles in an atom's nucleus that have mass but no charge. Chadwick proved their existence by tracking particle radiation.

The Neutronic Ear, or Personal Sound Amplification Product, was invented by American entrepreneur Michael Nehr. In 2001, Nehr was arrested in the state of Pennsylvania and charged with multiple felony counts related to his sales of the Neutronic Ear.

Atoms have positive protons, no charge neutrons and negative electrons. The positive and the negative describes the charge of the atom.

The sum of protons and neutrons is the mass number. The mass of an atom is contained mainly within the nucleus where the protons and neutrons live. An electron's mass does not contribute significantly to the mass of the atom.
