3. Matter and Its States Solid A substance in which atoms move very slow. Liquid A substance in which atoms are paces really closely together. 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. A substance in which atoms move really fast

4. Examples of the States of Matter Solid Solid Liquid Liquid Gas 1.Oxygen 2.Carbon Dioxide 3.Smoke 4.Steam 5.Water Vapor

5. Properties Physical Property Is when something can be observed without changing the identity of the substance. Chemical Property Is when something changes into a completely different substance. Property- Is how you identify something based on its appearance such as its color, shape, size, density, hardness, and state. 1.Freezing Point 2.Boiling Point 3.Smell 4.Color 5.Density 1.Iron Rusting 2.Bread Rising 3.Gasoline Burning 4.Eggs Cooking 5.Milk Going Bad

6. Changes Physical Change Is a change in form, shape or state and is easy to change back to its original state. Chemical Change Is when bonds have changed, and the substance forms into a new chemical. 1.Hydrogen Burned to Oxygen 2.Cooking 3.Expired Food 4.Silver Tarnishing 5.Burning wood 1.Solid to liquid 2.Liquid to gas 3.Solid to Gas 4.Gas to liquid 5.Liquid to Solid Change- Is when something becomes a new thing or a different thing.

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. 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. Element--- What is an Element 1.Krypton 2.Hydrogen 3.Neon 4.Copper 5.Iron An Element is a substance composed of atoms having an identical number of protons in each nucleus. Examples

9. Compounds- What is a Compound? 1.Salt 2.Plastic 3.Cotton 4.Wood 5.Steal A compound is when something comes together with another thing and they combine a whole of something else. A compound is when something comes together with another thing and they combine a whole of something else. Examples

10. What is the periodic table? How do I read/use the Periodic Table? 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. 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.

11. Substances and Mixtures Substances Is something that has mass and takes up space. Mixtures A mixture is the outcome of two or more substances mixed together 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 Is when you can actually see the different things that are in the mixture. It isn’t mixed evenly. Homogenous Is when you can’t really see the stuff in the mixture. It is mixed evenly. Examples 1.Salad (Heter.) 2.Orange Juice (Homo.) 3.Salt water (Heter.) 4.Water (Homo.) 5.Chunky Soup (Heter.)

13. Solutions Solvent A solvent is substance that can dissolve in another substance. Solute Is a substance that has dissolved in another substance. 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. Examples 1.Iced Tea-solute 2.Sea Water-solute 3.Lemonade-solute 4.Vinegar-solute 5.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 Solubility is the maximum amount of a solute which will dissolve in a given amount of solvent at a fixed temperature
