Definitions

Helium :For other uses of this term, see Helium (disambiguation) . Helium (He) is a colorless, odorless, tasteless, non-toxic, inert monatomic chemical element that heads the noble gas series in the periodic table and whose atomic number is 2. Its boiling and melting points are the lowest more

Diamond

Diamond Diamond is an allotrope of carbon . It is the hardest known natural material and the third-hardest known material after aggregated diamond nanorods and ultrahard fullerite . Its hardness and high dispersion of light make it useful for industrial applications and jewelry . Diamon more

Francium

Francium Francium (), formerly known as eka-caesium and actinium K , is a chemical element that has the symbol Fr and atomic number 87. It has the lowest known electronegativity of all known elements, and is the second rarest naturally occurring element (after as more

Metabolism

Metabolism adenosine triphosphate , a central intermediate in energy metabolism. Metabolism is the set of chemical reaction s that occur in living organism s in order to maintain life . These processes allow organisms to grow and reproduce, maintain their structures, and respond to their environme more

Equipartition theorem

Equipartition theorem peptide . The jittery motion is random and complex, and the energy of any particular atom can fluctuate wildly. Nevertheless, the equipartition theorem allows the average kinetic energy of each atom to be computed, as well as the average potential energies of many vibrationa more
