Across
  1. 2. a positively or negatively charged particle
  2. 5. Covalent Bond- a Covalent bond where each side of the atom has a positive and negative charges.
  3. 6. negative ion
  4. 7. must have a neutral charge.
  5. 10. (Size of atom)
  6. 12. the process of losing or gaining elections. to formions.
  7. 14. (electron) diagrams the valence electrons of an atom
  8. 15. Every atom wants" a full outer valance shell of 8 elections.
  9. 16. 2 atoms share 2 sets of electrons.
  10. 17. a positively charged ion
  11. 18. - Bonds formed between Atoms that share a pair of electrons
  12. 20. bond created when I atom takes an electron away from another atom creating Oppositely charged particles that bond strongly.
  13. 22. are more stable than the elements that make then
  14. 23. a measure of how strongly an atom attracts loose electrons.
Down
  1. 1. the amount of energy needed to Ionization energy - the ar remove an electron from 1 atom of the element.
  2. 3. strong bonds between I or more cations and I or more anions (an electron is lost from I and taken. by the other
  3. 4. Molecules-A Molecule made of 2 of the Same atom. H2, N2, O2, F2, Cl2, B2, I2, Atz )
  4. 8. Molecule made of Z of the same atom
  5. 9. covalent bond - a covalent bond where I side of the Molecule is slightly positive & the other slightly negative.
  6. 11. a negatively charged particle
  7. 13. 2 atoms share 3 sets of electrons
  8. 19. bond. bond created when 2 atoms Share a pain of electrons.
  9. 21. positive ion
  10. 24. an atom that lost or gained an electron
