Atomic mass:The standard atomic weight of an element is the average mass of the element written in atomic mass units (amu). Even though each atom has roughly a whole number of atomic mass units, you will notice that the atomic mass on the periodic table is a decimal; that's because the...
Amedeo Avogadrocreated the word "molecule". What is the smallest molecule? The smallest molecule isdiatomic hydrogen (H2), with a bond length of 0.74 angstroms. Macromolecules are large molecules composed of smaller subunits; this term from biochemistry refers to nucleic acids, proteins, carbohydrates...
