Across
- 1. Anything that has mass and takes up space.
- 2. the area around a magnet where magnetic forces act on objects
- 5. Neutrally charged particles within the nucleus with a mass similar to protons. They act as a "nuclear glue" and, along with protons, define an element's isotope and atomic mass.
- 6. Materials like iron that can be magnetized due to their internal domains
- 8. the space occupied by an object
- 9. Positively charged subatomic particles located in the nucleus. The number of protons determines the element's atomic number.
Down
- 1. a tiny region where atomic magnetic fields are grouped and aligned
- 3. the mass of matter combined within a volume
- 4. magnet produced by electric current
- 7. Negatively charged particles found in shells surrounding the nucleus. Electrons are responsible for chemical bonds and interactions.
