Elements can be defined based on the singularity of substances that make up its composition, the number of protons, the number of electrons and the atomic weight. Elements cannot be broken down into simpler substances. The number of protons and electrons will be unique for each element. The atomic weight is determined by the number of protons and neutrons.
