  2. Table of contents • Matter and its states • Physical and Chemical Properties • Physical and Chemical Changes • Atoms • Elements • Compounds • The Periodic Table • Substances and Mixtures • Heterogeneous and Homogenous Mixtures • Solutions • Solubility

  3. Matter and Its States Matter- Something that occupies space and can be observed by one or more senses; a physical body, a physical substance, or the universe as a whole. Solid Liquid A substance in which atoms are paces really closely together. • A substance in which atoms move very slow. Gas • A substance in which atoms move really fast

  4. Examples of the States of Matter Gas Solid Liquid Water Milk Orange Juice Soda Coffee Oxygen Carbon Dioxide Smoke Steam Water Vapor • Cookie • House • Computer • TV • Couch

  5. Properties Property- Is how you identify something based on its appearance such as its color, shape, size, density, hardness, and state. Physical Property Chemical Property Is when something changes into a completely different substance. • Is when something can be observed without changing the identity of the substance. Freezing Point Boiling Point Smell Color Density Iron Rusting Bread Rising Gasoline Burning Eggs Cooking Milk Going Bad

  6. Changes Change- Is when something becomes a new thing or a different thing. Physical Change Chemical Change Is when bonds have changed, and the substance forms into a new chemical. • Is a change in form, shape or state and is easy to change back to its original state. Hydrogen Burned to Oxygen Cooking Expired Food Silver Tarnishing Burning wood Solid to liquid Liquid to gas Solid to Gas Gas to liquid Liquid to Solid

  7. Atoms--- What is an Atom? A unit of matter, the smallest unit of an element, having all the characteristics of that element and consisting of a dense. They also surround one big positively charged Nucleus.

  8. Examples Element--- What is an Element • Krypton • Hydrogen • Neon • Copper • Iron An Element is a substance composed of atoms having an identical number of protons in each nucleus.

  9. Examples Compounds- What is a Compound? • Salt • Plastic • Cotton • Wood • Steal A compound is when something comes together with another thing and they combine a whole of something else.

  10. What is the periodic table? The Periodic Table is basically a chart of chemical elements. It also gives you all of the information you need to know about the element. It gives it name, atomic number, atoms, their mass, and the symbol o their name. Also it arranges them into groups/columns based on their structure and property. How do I read/use the Periodic Table? What are trends/patterns of the Periodic Table? In Chemistry, periodic trends patterns in the periodic table are the tendencies of certain elemental characteristics to increase or decrease as one progresses from one corner of the Periodic table of elements. • The periodic table is used mainly by scientists, teachers, and students to quickly locate important information about the elements. The periodic table usually tells us the symbol, atomic mass, and the atomic number.

  11. Substances and Mixtures Substances Mixtures A mixture is the outcome of two or more substances mixed together • Is something that has mass and takes up space. The difference between Substances and Mixtures is that a substance is just a substance, but a mixture is many substances stuck together. So basically a mixture is just one big substance.

  12. Mixtures Heterogeneous Homogenous Is when you can’t really see the stuff in the mixture. It is mixed evenly. • Is when you can actually see the different things that are in the mixture. It isn’t mixed evenly. Examples Salad (Heter.) Orange Juice (Homo.) Salt water (Heter.) Water (Homo.) Chunky Soup (Heter.)

  13. Solutions A solution is mixture of two or more substances that create a homogenous mixture, which may be a solid, liquid, gas, or even a combination of all of these. Solvent Solute Is a substance that has dissolved in another substance. • A solvent is substance that can dissolve in another substance. Examples Iced Tea-solute Sea Water-solute Lemonade-solute Vinegar-solute Carbonated water-solvent

  14. Solubility-What is Solubility? Solubility is the maximum amount of a solute which will dissolve in a given amount of solvent at a fixed temperature
