Across
  1. 6. subatonic partical which has a neautral charge
  2. 8. electrons the electrons in the outermost shell or energy level of an atom
  3. 11. smallest unit of ordinary matter that forms a chemical element
  4. 13. row of chemical elements
  5. 14. small dense region consisting of protons and neutrons at the center of an atom
  6. 15. elements on the periodic table that are malleable, lose electrons easily, good conductors of heat/electricity, and typically appear reflective
Down
  1. 1. look like brittle metals but their chemical behaviors is distinctly nonmetals
  2. 2. CLOUD region of negative charge surrounding an atomic nucleus
  3. 3. represents the 3-dimentional space surrounding the nucleus where electrons are most likely to be
  4. 4. stable subatonic partical with a positive electric charge
  5. 5. the physical property of a material associated with the ability to be hammered thin or stretched into wire without breaking
  6. 6. chemical element that generally lacks a predominance of metalic properties
  7. 7. negatively charged subtonic particles located in orbitals surrounding the nucleus
  8. 9. column of elements in the periodic table
  9. 10. the ability of a solid to bend or be hammered into other shapes without breaking
