Across
  1. 3. a bond formed when two or more nonmetals share electrons
  2. 6. a bond created when the electrons in metals become delocalized and are shared throughout the entire substance
  3. 9. the smallest unit of matter that can exist independently
  4. 10. a type of matter that is made of all one atom or molecule
  5. 11. the negatively charged part of an atom; responsible for creating chemical bonds with other atoms
  6. 12. a force created by the sharing or movement of electrons between atoms; holds atoms together creating molecules
  7. 14. two or more atoms that are held together with chemical bonds
  8. 16. a type of solid made of atoms or molecules that are bonded in a pattern
  9. 17. the one hundred and eighteen different types of atoms that are known to exist
  10. 18. a type of solid made of repeating molecules
  11. 19. a larger matter created when atoms or molecules are not rigidly bonded and are not attracted to the other atoms or molecules around them; these will fill their container and have not fixed volume
  12. 20. the part of the atom that has no charge; responsible for reducing the repelling force of protons
  13. 21. a type of matter that is made of two or more types of atoms or molecules
Down
  1. 1. the positively charged part of an atom; responsible for holding electrons in place
  2. 2. a bond formed when a metal donates electrons to a nonmetal creating oppositely charged ions that attract to each other
  3. 4. the center part of an atom
  4. 5. a larger matter created when atoms or molecules are bound in fixed positions; these have constant shapes and volume
  5. 7. a representation of an atom depicting how many protons and neutrons are in the center of the atom with the arrangement of electrons in shells around the nucleus
  6. 8. a larger matter created when atoms or molecules are not rigidly bonded, but have a weak attraction for the other atoms or molecules around them; these will take the shape of their container, but have a fixed volume
  7. 10. a chart organizing the elements by common characteristics
  8. 12. a description of the type and number of atoms in a molecule
  9. 13. a type of solid made of atoms or molecules that are bonded randomly, in no apparent pattern
  10. 15. shells the outside part of the atom; represented as orbits that electrons circle the center of the atom in
