Down
- 1. negatively charged ion
- 2. atoms of a metal are somewhat fixed in position in a crystal lattice, while outer electrons move freely throughout the lattice
- 4. particle composed of two protons and two neutrons
- 6. particle that represents an emitted electron (-1 charge)
- 9. radiation with the lowest penetrability and the lowest ability to cause harm
