element
a fundamental substance that together composes matter
compounds
chemical combinations
bulk elements
elements that the body requires in large amounts
What are the main bulk elements?
carbon, hydrogen, oxygen, sulfur, and phosphourus
trace elements
elements required in small amounts
ultratrace elements
elements that are toxic in large amounts but may be vital in very small amounts
atoms
the smallest complete units of the elements
nucleus
the dense core of an atom that is composed of protons and neutrons
electrons
a small negatively charged particle that encircles the nucleus of an atom, so small they have almost no weight at all
proton
positively charged particle in an atomic nucleus
neutron
electrically neutral subatomic particle,
atomic number
the number of protons in the atoms of particular elements
