1 Whats a Matter?

2 What is Matter? Matter: Anything that takes up space and has mass Atom: Basic unit of matter Chemistry: The study of matter and all the changes it undergoes. Element: Kind of atom (oxygen, hydrogen etc…) Molecule: 2 or more atoms Compound: 2 or more elements Is O 2 a compound or molecule? Is H 2 O a compound or element?

3 What Changes Does Matter Undergo? Physical: The substance is still the same Chemical: A new substance is formed

4 What is a solid, liquid or gas? Help Marvin the Martian understand what a solid, liquid and gas are! Draw what solids, liquids, gases look like What would happen if we increase the temperature? What would happen if we decreased the temperature?

5 What does an atom look like? Atoms contain a nucleus with protons (+) and neutrons (no charge) and have electrons (-) flying around Neils Bohr: Proposed the planetary model after studying a hydrogen atom in 1915.

6 Electron Cloud Theory

7 How do compounds form? Ionic Bond: An electron is transferred from one element to another (metal to nonmetal) Covalent Bond: Electrons are shared (nonmetal to nonmetal) Metallic Bond: Sea of electrons (Metal to Metal)

8 CLASSIFYING MATTER

9 How do we use the periodic table of elements? Group IA: Alkali Metals Group VIIIA (O): Noble Gases Group IIA: Alkaline Earth Metals Other Nonmetals Group B: Transition Metals Metalloids Group VIIA: Halogens Other Metals

10 How do we use the periodic table? (Number of protons/electrons) ( protons + neutrons)

11 Which element has the atomic # 10? Which element has a mass of 4 amu? Which element is in period 3 and is a Noble Gas? Cu +2 How many protons? How many electrons? How many neutrons? Who Am I?

12 What are acids and bases? ACIDS BASES TASTESOURBITTER FEELSTINGSSLIPPERY REACTIONS YES / METAL NO / METALS CONDUCTS ELECTROLYTE ELECTROLYTE

13 HOW DO WE MEASURE ACIDS AND BASES? INDICATORS A SUBSTANCE THAT TURNS ONE COLOR IN AN ACIDIC SOLUTION AND ANOTHER COLOR IN A BASIC SOLUTION SOME INDICATORS ARE: LITMUS: DYE THAT COMES FROM A LICHEN PHENOLPHTHALEIN: INDICATES ONLY BASES UNIVERSAL INDICATOR: ACID, NEUTRALS, BASES CABBAGE JUICE: ACIDS, NEUTRAL, BASE
