NATS 1840 Lecture Notes - Lecture 2: Carbon-14, Kinetic Energy, Atomic Number
Document Summary
Laws of nature for matter and energy are the ground rules that ecological processes must follow. Matter: anything that takes up space and has mass. Composed of atoms of elements which interact chemically with one to form more complicated molecules of compounds. Chemical notation: the element with atomic number =6 carbon symbols c explicitly 12=mass 6=atomic # 6 neutron = carbon 12. Isotope of carbon 14=mass 6=atomic # neutron = 8 =carbon 14. Charge would be indicated on right-hand side superscript. The last column of the periodic table features chemically insert elements with atomics 2,10,18,36,54,86. Atoms become more chemically stable if they have the same # of electrons in the last column. Energy: consider difference between moving and non-moving object. Work: is done when matter moves or changes its state of motion because of the application of force upon it. Energy: the ability of a system to move matter through some distance ex.
