Step 1 of 3

Chemistry 8/30/16 Matter and Measurement  matter occupies space and has mass  pure substances have definite composition and properties as well as a formula  elements are made up of one thing  compounds are made up of multiple element and are chemically bonded in fixed proportions  atoms are the building blocks of matter  Law of constant composition or definite proportions  gas (no shape or volume), liquid (no shape but has volume), and solid (has both shape and volume)  118 known elements >82 are unstable  an element is a substance that can’t be separated into simpler substances by chemical means  about 90 elements occur naturally (up to 92 on the periodic table except 43&61)  28 newer elements were created by scientists including “missing” elements and more than 20 “transuranic elements” (93­118)  mixture 2 or more substances that retain their identities o homogenous ­ same throughout o heterogeneous – is not the same throughout o In the graph Below the red line indicates no and the blue line indicates yes Homogenous Mixture Homogenous (Variable Element Composition) Pure Substance Matter (Separated (Is it uniform) Chemically) Heterogeneous
