Electron
29 linksSubatomic particle whose electric charge is negative one elementary charge.
Subatomic particle whose electric charge is negative one elementary charge.
The electron's mass is approximately 1836 times smaller than that of the proton.
Neutron
35 linksThe neutron is a subatomic particle, symbol or, which has a neutral (not positive or negative) charge, and a mass slightly greater than that of a proton.
Atom
25 linksSmallest unit of ordinary matter that forms a chemical element.
Smallest unit of ordinary matter that forms a chemical element.
The nucleus is made of one or more protons and a number of neutrons.
Atomic nucleus
22 linksThe atomic nucleus is the small, dense region consisting of protons and neutrons at the center of an atom, discovered in 1911 by Ernest Rutherford based on the 1909 Geiger–Marsden gold foil experiment.
Quark
21 linksType of elementary particle and a fundamental constituent of matter.
Type of elementary particle and a fundamental constituent of matter.
Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons, the components of atomic nuclei.
Deuterium
18 linksOne of two stable isotopes of hydrogen (the other being protium, or hydrogen-1).
One of two stable isotopes of hydrogen (the other being protium, or hydrogen-1).
The nucleus of a deuterium atom, called a deuteron, contains one proton and one neutron, whereas the far more common protium has no neutrons in the nucleus.
Elementary particle
16 linksElementary particle or fundamental particle is a subatomic particle that is not composed of other particles.
Elementary particle or fundamental particle is a subatomic particle that is not composed of other particles.
Subatomic constituents of the atom were first identified in the early 1930s; the electron and the proton, along with the photon, the particle of electromagnetic radiation.
Hadron
15 linksComposite subatomic particle made of two or more quarks held together by the strong interaction.
Composite subatomic particle made of two or more quarks held together by the strong interaction.
Most of the mass of ordinary matter comes from two hadrons: the proton and the neutron, while most of the mass of the protons and neutrons is in turn due to the binding energy of their constituent quarks, due to the strong force.
Hydrogen
14 linksChemical element with the symbol H and atomic number 1.
Chemical element with the symbol H and atomic number 1.
For the most common isotope of hydrogen (symbol 1H) each atom has one proton, one electron, and no neutrons.
Chemical element
12 linksA chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species.
