One measure of several that reveals the extent of our existence is the
We all live in a world of magnetic attraction and electrical flow.
People sense that flow as color, heat and pressure but the energy contained in the world can be thought of as disturbing an inherent state of rest.
The depiction of a hydrogen atom here shows that it is never at rest and as the electron (blue) speeds about the atomic nucleus (red = one proton) there is an exchange of electromagnetic radiation. That radiation has a specific wavelength, and frequency. H or hydrogen is the most abundant atomic element in the universe and the least massive because it contains --most often-- only one positively charged entity called a proton.
The disturbance can be measured by the wavelength of the disturbance, the frequency of the disturbance, and the impact of that disturbance on solutions of elements, compounds or atoms.
Traditionally atoms were conceived of as little solar systems with electrons (shown here in red and "-") as small planets orbiting the dense nucleus or mass of protons (shown here in blue and "+") or neutrons (small and grey-white) that do not have an electrical charge but are slightly more massive than the proton. This planetary model however is less accurate than what quantum mechanics and nuclear research has discovered experimentally. That is because the atom does not behave like a start system and electrons are not solid or gaseous planets.
Instead the neutron is drawn to display how it decays into a proton and an electron with an enormous release of radiation or high frequency energy. In addition there is evidence for the behavior of electrons that are not similar at all to the way planets orbit a star in a solar system. The figure below suggests that as they move at the speed of light over a distance of one angstrom unit that the electrons are quite bizarre in their motion.

A compound is common in nature and describes the arrangement of atoms in certain molecules.
Whether as ice, vapor gas, or liquid, water is always composed of two hydrogen atoms and one oxygen atom.
