Forms of matter ppt
- 1. Forms of matter What matter is made of.
- 2. Pure forms of matter Elements- substance made up of only one kind of atom. All atoms are the same in that they have the same number of protons. Example Sodium or symbol Na has 11 protons and 11 electrons. Elements are pure substance that can not be broken down by ordinary chemical or physical means.
- 3. Symbols Representation of an elements. H for hydrogen or O oxygen Na for sodium or Fe for Iron
- 4. Pure substance Compounds- When two or more elements combine chemically to form a new substance.The compound formed has a completely new set of physical and chemical properties. Example when Hydrogen symbol H , which is flammable combines with Oxygen symbol O which supports combustion forms Water H O Combine in definite proportion and ratio’s.
- 5. Formulas Shows that two or more elements have combined to form a compound. FeO Iron oxide H2O water (* Dihydrogen oxide) Na Cl salt sodium chloride KCl light salt Potassium chloride MgO Magnesium oxide
- 6. Mixtures Two or more substance that are combined physically. Mixed together, stirred together, dissolved into something, melted together. Two types of mixtures
- 7. Homogeneous mixtures Mixtures where the substance has the same appearance and properties throughout. Examples- ice tea, kool-aid, jello, salt water, or sugar water. Most of these kinds of mixtures are where substance have been dissolved. There are two parts to dissolving or called Solution a. solute- the stuff being dissolved. b. solvent- the stuff doing the dissolving.
- 8. Heterogeneous Mixtures Mixtures -where the substances are unevenly distributed. Examples- cement, spaghetti and meat ball, air, milk. Most substance in the universes are this type or kind of matter. Including your body, the table your at.
- 9. Periodic Table Metal- Most of the elements are metals. They generally have physical properties like shinny luster ( how light reflects from the surface), conduct heat, conduct electricity, solid. Chemical properties- will not react with other metals, will react with non-metals an some metalloids.
- 10. Metalloids- have characteristics of both metals and non metals. Example are Silicon (Si) , Boron ( B ) Non-metals- Most are gases- they do not conduct heat or,electricity. Oxygen ( O ), Chlorine ( Cl ) and Iodine ( I ).
