Document Summary
Chemistry - science that deals with the structure of matter, including atom structure, chemical building blocks and how atoms combine to form complex. Matter join together to form chemicals with different characteristics smallest unit of matter. Anything that takes up space and has mass. H, c, o, n are most common (96% of body elements) Mass number (atomic weight/mass) = total number of protons and neutrons atoms are electrically neutral (equivalent number of protons and electrons) distinguished based on atomic numbers. Atomic number = number of protons in an atom. *elements are a pure substance composed of only 1 type of atom. Atoms of an element with the same number of protons but a different number of neutrons. H, c and uranium are naturally occurring isotopes (forms of radiation, which can either cause cancer or in small amounts, can be utilized in diagnostic technology) Can emit alpha, beta and gamma rays.
