  1. 5. - electron maintained in orbit by
  2. 8. Number of waves passing a point per second.
  3. 9. The process of removing or adding an electron to form ions.
  4. 12. A high-energy electromagnetic wave capable of penetrating matter.
  5. 14. - two or more atoms joined by chemical bonds, the smallest
  6. 15. - Energy traveling through space or matter.
  7. 17. Distance between wave crests; shorter = higher energy.
