Across 5. Indicates number of valence electrons around an atom. 7. Elements that have charactersitics of both metals and nometals. 9. Negative atom. 11. P1/V1=P2/V2 14. The elctrons in the highest level . 16. Electrons share in order to follow the octet rule. 18. Makes up the periodic table . 19. Positively charged ions, formed when elctrons are lost. 21. Elements that are made in a lab. 23. Elements need 8 electrons to be happy. 24. PV=nRT

Down 1. Negatively charged ions, Formed when electrons are gained . 2. P1V1/T1=P2V2/T2 3. Makes up everything. 4. Atoms transfer or accept electrons from another. 6. V1/T1=V2/T2 7. These conduct heat and electricity . 8. Atoms transfer or accept electrons. 10. This shows all the elements organized by their properties . 12. P1/T1=P2/T2 13. The number of protons in an atom. 15. These are poor conductors of heat and electricity. They are dull and brittle. 17. The small part of a molecule . 20. Positive atoms . 22. Most of the elements are in this state at room tempeture.
