the compound we call water is created by combining the elements hydrogen and oxygen. One molecule of water is always made up of two hydrogen atoms and one oxygen atom. This is why water is referred to as H₂O in science. Water is created when elements chemically...
you wouldn’t consider it a molecule, as it is in fact a huge lattice network of individual sodium chloride compound particles, without a clear number of atomic nuclei. The same thing is true if you look at a drop of water; you aren’t looking at a molecule of water, but rather a h...

, James Maxwell defined atom and molecule: "An atom is a body which cannot be cut in two; a molecule is the smallest possible portion of a particular substance." Since molecules were named before their true nature was discovered, it led to what is now an inexact and debated definition....
Definition: By its classical definition, a molecule is the smallest particle of a substance that retains the chemical and physical properties of that substance. They are composed of two or more atoms, a group of like or different atoms held together by chemical forces. ...
What is a molecule? Despite being a standard scientific concept, it’s virtually impossible to agree a satisfactory definition, says Philip Ball In science, as in life, words often acquire meaning through usage rather than through definition. We use ‘species’ and ‘force’ without being ...
