Atomic NumberAtomic Number
The atomic number of an atom is the total number of protons.
The atomic weight of an atom is the total number of protons plus neutrons.
Chemical properties of an element are determined by the number of electrons in the outermost energy level of an atom.

MetabolismMetabolism
Metabolism refers to all the chemical reactions that occur in a living system.Anabolism, or reactions involving the synthesis
of compounds.Catabolism, or reactions involving the
breakdown of compounds.
