VOCABULARY

  1. chemical bond - the force that holds two atoms together
  2. ductile - A term used to describe a material that can be pulled out into a long wire.
  3. solubility - the ability of one substance to dissolve in another substance
  4. malleable - easy to change shape or bend
  5. corrosion - the gradual wearing away of a metal element due to a chemical reaction
  6. ph - a measure of how acidic or basic a solution is
  7. reactivity - the ease and speed with which an element combines, or reacts, with other elements and compounds
  8. chemical reaction - the process that changes one set of chemicals into another set of chemicals
  9. chemical properties - characteristics that can only be observed when one substance changes into a different substance
  10. physical properties - the characteristics of a substance that can be observed or measured without changing the substance
  11. physical change - a change of matter from one form to another without a change in chemical properties
  12. chemical change - a change in which one or more substances combine or break apart to form new substances
  13. precipitate - a solid that forms from a solution during a chemical reaction
  14. chemical equation - A representation of a chemical reaction that uses symbols to show the relationship between the reactants and the products
  15. reactants - A starting material in a chemical reaction
  16. products - The elements or compounds produced by a chemical reaction.
  17. acids - they contain higher concentrations of hydrogen ions than pure water and have pH values below 7
  18. bases - Compounds that reduce the concentration of hydrogen ions in a solution. They are above 7 on the ph scale
  19. exothermic process - chemical reaction or physical change that releases heat
  20. endothermic process - chemical reaction or physical change that absorbs heat
  21. flammability - the ability of a substance to burn
