  • Transcript of "Atoms and mxtures pres."

    1. 1. Atoms And what they make
    2. 2. Atoms An atom is the smallest, most basic particle from which matter is created. Just think: A sheet of paper is about 10,000 atoms thick There are 2,000,000,000,000,000,000,000 atoms of oxygen in a single drop of water There are about a billion billion atoms in the period at the end of a sentence in your textbook
    3. 3. Molecules A molecule is a group of 2 or more atoms that are held together by chemical bonds A chemical bond is the force that holds two atoms together Molecules can contain the same or different atoms (as long as there are 2 or more)
    4. 4. Pure Substances A pure substance is made of only one type of matter and has a definite set of properties. Every sample of pure substance is the same, no matter what form it is in Pure substance can be either : Elements Compounds
    5. 5. Elements An element is a pure substance that is made from one type of atom (by one or more atoms.) Elements cannot be broken down into other substance by chemical or physical means Elements have their own specific physical and chemical properties Examples: Carbon (C), Oxygen (O), Hydrogen (H)
    6. 6. Compounds A compound is a pure substance that is made of 2 or more elements that are chemically combined in a set ratio Compounds can be represented by a chemical formula Compounds have properties that are different from the elements that make them CH3COCH3 C8H10N4O2 H 2O Caffeine CHCl3 Acetone CH3CH2OH Water Chloroform (Nail Polish Remover) Ethanol
    7. 7. Mixtures A mixture is made of two or more substances that are together in the same place but not chemically combined. Each individual substances keep their separate properties Ex.: beach sand, lemonade There are 2 types of mixtures: Heterogeneous Mixtures - you can see the different parts Homogeneous Mixtures - these are so evenly mixed that you can’t see the different parts (ex. solution)
    8. 8. Concept Map Types of Matter Solution, Element, Mixture, Atoms, Homogeneous Mixture, Pure Substance, Heterogeneous Mixture, Compound
