Chemical element
5 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.
Chemical compound
5 linksA chemical compound is a chemical substance composed of many identical molecules (or molecular entities) composed of atoms from more than one element held together by chemical bonds.
Chemical reaction
5 linksA chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another.
Chemical formula
5 linksWay of presenting information about the chemical proportions of atoms that constitute a particular chemical compound or molecule, using chemical element symbols, numbers, and sometimes also other symbols, such as parentheses, dashes, brackets, commas and plus and minus (−) signs.

Chemical formulae can fully specify the structure of only the simplest of molecules and chemical substances, and are generally more limited in power than chemical names and structural formulae.
Molecule
5 linksGroup of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Group of two or more atoms held together by attractive forces known as chemical bonds; depending on context, the term may or may not include ions which satisfy this criterion.
Earlier definitions were less precise, defining molecules as the smallest particles of pure chemical substances that still retain their composition and chemical properties.
Chemistry
3 linksScientific study of the properties and behavior of matter.
Scientific study of the properties and behavior of matter.
It is a natural science that covers the elements that make up matter to the compounds composed of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during a reaction with other substances.
Properties of water

A polymer ( Greek poly-, "many" + -mer, "part")
is a substance or material consisting of very large molecules called macromolecules, composed of many repeating subunits.
Chemical composition
0 linksChemical composition refers to identity and number of the chemical elements that make up any particular compound.
Chemical composition refers to identity and number of the chemical elements that make up any particular compound.
The chemical composition of a pure substance corresponds to the relative amounts of the elements that constitute the substance itself.
