# The smallest unit of a substance that can exist alone and retain the character of that substance.
# Compound of two or more atoms, the smallest unit of chemical compounds.
# The smallest particle of a substance that has all of the physical and chemical properties of that substance. Molecules are made up of one or more atoms. If they contain more than one atom, the atoms can be the same (an oxygen molecule has two oxygen atoms) or different (a water molecule has two hydrogen atoms and one oxygen atom). Biological molecules, such as proteins and DNA, can be made up of many thousands of atoms.
# The smallest division of a compound that still retains or exhibits all the properties of the substance.
# The smallest particle of a substance that retains the properties of the substance and is composed of one or more atoms.
# The smallest unit into which a substance can be divided and still retain the composition and chemical properties of that substance.
# The smallest particle of a compound that has all the chemical properties of that compound. Molecules are made up of two or more atoms, either of the same element or of two or more different elements. Ionic compounds, such as common salt, are made up not of molecules, but of ions arranged in a crystalline structure. Unlike ions, molecules carry no electrical charge. Molecules differ in size and molecular weight as well as in structure.
# a substance composed of two or more atoms held together by chemical bonds.
# The smallest unit of a compund that can exist by itself and retain all its chemical properties.

# A chemical species defined by its fundamental properties and including other properties and references. See the Molecule property data format table.

# a group of atoms arranged to interact in a particular way; one molecule of any substance is the smallest physical unit of that particular substance.

# a small unit of matter made up of atoms. A molecule is the smallest unit of a substance that retains its unique characteristics.
# The smallest particle that has any of the chemical or physical properties of an element or compound.
# the smallest unit of an element or compound. A molecule is made up of at least two atoms.
# In propositional logic, a compound proposition as opposed to a simple proposition or atom. See atom; compound proposition. Monotonicity. The property of a system by which adding new wffs to a set of wffs cannot invalidate previously valid derivations from that set. If A is any wff, and Γ and Δ any sets of wffs, then a system is monotonic iff Γ A implies Δ,Γ A. In non-monotonic logics, derivations valid from Γ can be invalid from Γ Δ. ...

# two or more elements that are chemically joined (Water is a molecule made from two atoms of Hydrogen and one atom of Oxygen.)
# A tightly bound collection of atoms held together by the electromagnetic fields of the atoms. Molecules, like atoms, emit and absorb photons at specific wavelengths.
# (L. diminutive of moles, a little mass) A unit of matter, the smallest portion of an element or a compound that retains chemical identity with the substance in mass. The molecule usually consist of a union of two or more atoms; some organic molecules containing a very large number of atoms.
# a combination of atoms, and also the basic building — block of DNA and RNA. Each molecule has its own shape and attaches only to certain other molecules to form the DNA helix.
# a group of atoms held together by chemical bonds; the typical units manipulated by nanotechnology.

# A chemically unique aggregate of at least two atoms (see also elements). The atoms are linked to each other by chemical (covalent) bonds. All matter is made up of molecules. Free atoms are rarely found but are important in the form of salts or metal ions in water.
# Two or more atoms contained together by covalent bonds. Includes chemical substances which are the building blocks of cells such as proteins, sugars and fats.
# The smallest particle, consisting of two or more atoms
http://www.the-mwg.com/html/glossary/gl ... view.shtml
# The result of two or more atoms combining by chemical bonding.
# group of atoms that are covalently bound to create a chemical structure
# (physics and chemistry) the simplest structural unit of an element or compound
# atom: (nontechnical usage) a tiny piece of anything
# In science, a molecule is the smallest particle of a pure chemical substance that still retains its chemical composition and properties. A molecule consists of two or more atoms joined by shared pairs of electrons in a chemical bond. It may consist of atoms of the same chemical element, as with oxygen (O2), or of different elements, as with water (H2O).
Please delete my triplets. I trapped in Debug Mode yesterday, so my posts were sent many times
