8.P.1 Chemistry
8.P.1.1 Elements, Compounds, and Mixture subunit-Classify matter as elements, compounds, or mixtures based on how the atoms are packed together in arrangements.
8.P.1.1 Vocabulary Terms
Matter- anything that has mass and volume
Atom- the basic building block of most of the matter around us; the smallest particle of an element that has all the properties of the element
Elements-one of the basic substances that combine to form all other substances; a substance that cannot be broken down into simpler substances by ordinary means
Compounds-a pure substance that forms when two or more different elements join chemically in a fixed proportion or ratio
Mixtures-matter made up of two or more substances that are NOT joined chemically
Heterogeneous- a mixture in which substances are NOT distributed evenly
Homogeneous-a mixture in which substances are distributed evenly
Solution-a homogeneous mixture in which one substance is completely dissolved in another substance
Solvent-in a solution, the substance that does the dissolving
Solute-in a solution, the substance that dissolves
Molecules- two or more atoms are joined together chemically.

8.P.1.2 Atomic Structure and the Periodic Table
Vocabulary-Matter
8.P.1.2-The Periodic Table
Explain how the physical properties of elements and their reactivity have been used to produce the current model of the Periodic Table of elements.
Conductivity- The ability of a material to conduct electricity or heat
Reactivity- the tendency of a substance to undergo chemical changes
Metals- An element that conducts heat and electricity well, is shiny, and can be hammered into sheets or drawn into wires
Nonmetals- an element that does not conduct heat or electricity well and is dull and brittle or gaseous
Metalloids- An element that has some properties of both metals and nonmetals
Periodic Table of Elements- A chart that organizes information about all the known elements according to their properties
Periods- A horizontal row in the periodic table
Groups- A vertical column in the periodic table; also called a chemical family
Subatomic particle-the three parts of an atom including protons, neutrons, and electrons
Proton- positively charged part of an atom
Neutrons-neutrally charged part of an atom
Electrons-negatively charged part of an atom
Nucleus- protons and neutrons are found in this part of an atom
