Water is made up of two different elements, 2 hydrogens and 1 oxygen, so H2O is a compound. Two oxygen atoms (O2) are two elements, but they are the same element, so O2 is a molecule. Iron oxide (Fe2O3), or rust, is made up of two different elements, 2 irons and 3 oxygens...
If rotaxanes (where a cyclic molecule remains threaded on a linear one because of bulky capping groups on the thread) are molecules, what about pseudorotaxanes, where there are no end caps and the threading is merely statistical, or held in place by weak interactions? One can clearly enginee...

A Compound is a substance formed from two or more different elements chemically combined. A Molecule is the smallest particle of a substance that retains its chemical properties, made of one or more atoms.
A covalent compound is amoleculeformed bycovalent bonds, in which theatomsshare one or more pairs ofvalence electrons. The Different Kinds of Compounds Chemical compounds are generally grouped into one of two categories: covalent compounds and ionic compounds. Ionic compounds are made up of electrica...
Today, a mole isAvogadro's numberof particles, which is exactly 6.02214076×1023. For all practical purposes, the mass of one mole of a compound in grams is approximately equal to the mass of one molecule of the compound in daltons. ...
