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 another term for a molecule. A molecule consists of two or more atoms (elements) that are bound together by either a covalent or an ionic bond. PurityThe purity of a compound can be examined using different chemical techniques. Examples may include thin layer chromatography or ...
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...

What is a molecule with a partial positive charge on one side and a partial negative charge on the other called? Molecules: Sometimes during bonding there is an unequal sharing of electrons. This unequal sharing of electrons results in a partial posi...
SMC(sheet molding compound) is a mixture of polymer resin, inert fillers (calcium carbonate, talc or wollastonite), fibre reinforcement, catalysts, pigments, stabilizers, release agents, and thickeners.
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 molecule is a group of two or more atoms joined by chemical bonds, whereas a compound is a substance formed by the chemical bonding of more than one type of element that exists in a fixed proportion.
A hydrocarbon chain is a molecule that consists of entirely hydrogen and carbon. They are the simplest of the organic compounds and may be a liquid, gas or solid. There are many types of hydrocarbon chains, including alkanes, alkenes, alkynes, cycloalkan
