BIOL 1010 Lecture Notes - Lecture 2: Scanning Tunneling Microscope, Higgs Boson, Elementary Particle
Document Summary
Properties result from the correct arrangement and interaction of parts within a system. The study of matter and the transformations it undergoes. Chemistry is a bridge between physics and biology. A substance consisting of two or more elements combined in a xed ratio. It has characteristics di erent from those of its elements. Make up 96% of living matter and include carbon, hydrogen, oxygen, and nitrogen. Trace elements: are required by an organism in only small quantities. #first images of atom were taken in the early 1980s by a scanning tunnelling microscope. The smallest unit of matter that still retains the properties of an element. A quark is a type of elementary particle and a fundamental constituent of matter. Quarks combine to form composite particles called hadrons, the most stable of which are protons and neutrons. This particle helps give mass to all elementary particles that have mass, such as electrons and protons.
