Physical and chemical properties
Chemical Properties-Flammability,creativity,These properties can only be observed during a chemical reaction,Describes mater based on ti ability to change into new matter with different properties.
Physical and chemical changes
Chemical change- One or more substance are changed into new substances that have new and different properties like burning fire.
Compound-Substances formed when two or more elements chemically combine.
Mixtures- Combination of two or more different substances mixtures but not combined like Bowl of cereal.
Groups and Periods
Periods-The periodic table have seven horizontal (left to right) rows know as periods.
Nonmetals-All metals are on the left.
Metalliods-Their between the metals and nonmetals the step-down
Atomic number,Atomic mass,Protons,Neutrons,Electrons ,Law of conservation of mass
Atomic Mass-The mass of an atom of a chemical element that is equivalent to the number in the atom.
Protons-It is the atomic number
Neutrons-The round of the atomic table
Electrons-Are the sum of protons in the atom
Law of conservation of mass-
Index fossils-A fossil used to determine the relative age of a rock layer or fossil.
Ice core-Long cylinder of ice drilled from glaciers that tell you when gasses made up the atmosphere at different point in time.
Geologic time scale-Science that deals with earth substance.
Relative Dating-Used to determine the relative order of when things existed does not provide absolute dating.
Absolute Dating-Used to determine the specific age of the object organism.
Virus-Are confided to living but they living things.
Bacteria-Microscopic living organism usually one-celled that can be found everywhere.
Fungi-Something that goes on you foot like wear wet socks.
Parasite-An organism that lives in or on organism of other species know as the host cell.
Epidemic-Is an outbreak of an infectious disease with an small population.
Pandemic-Is a outbreak of an infectious disease that effects a large population.
Prevention/Treatment-Prevention is stopping something form happening. Treatment is Something that help get better.
Biotechnology -The use of living cells,bacteria, etc. to make useful products like crops.
