  1. 1. Negatively charged particles in an atom that are located outside of the nucleus.
  2. 8. The temperature at which a liquid turns into a solid when cooled.
  3. 11. an insoluble solid that emerges from a liquid solution.
  4. 12. The measure of how much matter an object contains.
  5. 13. A state of matter where the molecules are very spaced out and able to move around freely.
  6. 15. The electrons are located in the _____ of the atom.
  7. 17. The measure of the amount of matter in a given volume.
  8. 19. the smallest piece of matter, can not be broken into smaller pieces, consists of a nucleus with protons and neutrons with electrons orbiting its nucleus.
  9. 20. Created the First periodic table, arranged it by increasing atomic mass
  10. 24. Same number of protons and electrons as the original element but different number of neutrons
  11. 25. Any change that affects the physical properties of a substance.
  12. 26. An object’s ability to dissolve
  13. 28. A state of matter where the molecules are packed closely together and vibrating.
  14. 29. A state of matter where the molecules are a little bit spaced out able to move a little freely.
  15. 31. reorganized the Periodic Table in the early 1900’s according to increasing atomic number so now the elements within a period change in a predictable way
  16. 33. When a substance releases energy making it hot
Down
  1. 2. When a substance absorbs energy making it cold
  2. 3. Any change that affects the chemical properties of substance.
  3. 4. The temperature at which a liquid boils and turns to vapor.
  4. 5. Same number of protons and neutrons as original element but different number of electrons.
  5. 6. repeating chemical and physical properties of elements change periodically with the atomic number of the elements
  6. 7. the number of protons in the nucleus of an atom, which determines the chemical properties of an element and its place in the periodic table.
  7. 9. a substance that increases the rate of a chemical reaction without itself undergoing any permanent chemical change.
  8. 10. The temperature at which a given solid will melt.
  9. 14. The mass of an atom, on the periodic table
  10. 16. The ability of a substance to burn or ignite, causing fire or combustion.
  11. 18. Any substance that has mass and takes up space by having volume.
  12. 21. used mathematical equations to describe the likelihood of finding an electron in a certain position. This atomic model is known as the quantum mechanical model of the atom.
  13. 22. an abbreviation or short representation of a chemical element
  14. 23. The amount of space that matter takes up.
  15. 25. Positively charged particles in the nucleus of an atom.
  16. 27. How shiny an objects is (how much light it can reflect)
  17. 30. How good electrons or heat moves through a substance
  18. 32. Has no charge, found in the nucleus of an atom
