Periodic Table
Atomic Number and Atomic Mass
Atomic mass is the mass of an atom of a chemical element that's equivalent to the number of protons and neutrons in the atom.
Protons, Neutrons, Electrons
Electrons- a stable subatomic particle with a charge of negative electricity, found in all atoms and acting as the primary carrier of electricity in solids.
Neutrons- a subatomic particle of about the same mass as a proton but without an electric charge, present in all atomic nuclei except those of ordinary hydrogen.
Groups and Periods
Periods- The periodic table has 7 horizontal rows known as periods.
Law of Conservation of Mass
Element, Compound, Mixture
Compound- a substance formed when two or more chemical elements are chemically bonded together.
Mixture- a combination of two or more pure substances in which each pure substance retains its individual chemical properties.
Physical/ Chemical Properties
Chemical Changes- A property or behavior of a substance when it undergoes a chemical change or reaction.
Physical and Chemical Changes
Chemical- Any change that results in the formation of new chemical substances.
Vocabulary
Compound- Substance formed when 2 or more elements are chemically combined.
Matter- Anything that has mass and takes up space.
Solution- A substance made as a result of mixing a solid and a liquid and the solid disolves.
Earth History
Law of Superposition
Relative and Absolute Dating
Absolute Dating- The process of establishing the age of an object determining the number of years it has existed. It gives an actual number to the age.
Half life and Radioactive Dating
Radioactive Dating- A technique used to date materials such as rocks or carbon, usually based on a comparison between the observed abundance of a naturally occurring radioactive isotope and its decay products, using known decay rates.
Index Fossils
Geologic Time Scale
Ice Cores
Vocabulary
Fossil Record- A record of the total number of fossils that have been discovered.
Relative- Used to compare things
Absolute- Exact
Unitarianism- The geologic principal that the same geologic process that operate today operated in the past to change earths surface.
Infectious Disease
Bacteria, Fungi, Virus, Parasite
Bacteria- A member of a large group of unicellular microorganisms that have cell walls but lack organelles and an organized nucleus, including some that can cause disease.
Fungi- Any of a group of unicellular, multicellular, or syncytial spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
Virus- An infective agent that typically consists of a nucleic acid molecule in a protein coat, is too small to be seen by light microscopy, and is able to multiply only within the living cells of a host.
Parasite- An organism that lives in or on another organism (its host) and benefits by deriving nutrients at the host's expense.
