1 Page 2 Word Science Chemistry Vocabulary –Elements of Matter #1 Definition Picture and Example An atom is the smallest particle of matter. 1. Atom -Matter is anything that has mass and takes up space -There are three states of matter - solid, liquid and gas -Each state of matter has properties that describe how it looks and acts 2. Matter 3. Element a pure substance in which all the atoms are the same (H) 4. Pure Substance all the atoms (element) or molecules (compound) are the same. 5. Molecule the smallest part of a compound that can exist (two or more atoms connected) 6. Compound a pure substance containing 2 or more elements connected chemically (H2O) Science Chemistry Vocabulary –States & Forms of Matter Word Definition Picture and Example 7. States of Matter Matter can be gas, liquid or solid and can change from one to another. The state of matter 2 Page 2 can change because of temperature or pressure A substance in which 8. Mixture components are mixed but don’t blend together 9. Homogenous Mixture A substance in which components are mixed and evenly blend together 10. Heterogeneous Mixture A substance in which components are mixed but don’t blend together 11. Physical Change A change in substances that have had a chemical reaction. The original substance is changed to a new substance and cannot easily be changed back Describe how chemicals react 12. Chemical Change with one another – chemical reactions, solubility, acidity, heat, flammability, oxidation (rust), toxicity Science Chemistry Vocabulary –Mixtures & Solutions # 3 Word Definition 13. Solution -When one substance is evenly mixed with another
-also known as a homogeneous mixture Picture and Example 3 Page 2 -The substance being dissolved 14. Solute -A solute is dissolved into a solvent
-Ex: sugar (sugar dissolved into hot water) -What something is being dissolved 15. Solvent into -Ex: the water (sugar being dissolved into hot water) 16. Saturated a solution that cannot hold any more solute at a given temperature 17. Suspension a mixture in which the component are dispersed but large enough to see and to settle out 18. Decanting Process for separation -To pour off the top layer without disturbing the layers below 19. Filtering Process for separation –To separate the solid from a liquid by poring it through a filter (such as paper or a sieve) 20. Distillation Process for separation - the process of vaporizing then condensing a liquid (to separate the parts) 21. Gas Photo #1 Draw a photo of sugar + glass of water Photo #2 Draw a photo of sugar dissolved Point arrow to the layer sugar on bottom Photo #1 Draw a photo of corn starch + glass of water Photo # Draw a photo of dissolved cloudy liquid of water and corn starch 4 Page 2 22.
