Across
  1. 4. Rows in the periodic table
  2. 5. Smallest particle something can be cut into while still retaining its properties.
  3. 6. What the elements are abbreviated to
  4. 7. 2 or more elements bonded together like a molecule
  5. 10. The mass of an atom shown at the bottom of every element box in the periodic table
  6. 13. Subatomic particles that orbit the nucleus and have a negative charge. Too small to be counted for the mass of the atom
  7. 15. Subatomic particle that is in the nucleus, and has a neutral charge. The number of protons determines the element. Can be calculated by subtracting protons from mass.
Down
  1. 1. Irregular atom where the number of neutrons are different
  2. 2. Electrons in the outermost energy ring
  3. 3. The mass of the atom, electrons are not included
  4. 8. The number of protons in an atom and how the periodic table is organized by
  5. 9. Subatomic particle that is in the nucleus, and has a positive charge. The number of protons determines the element.
  6. 11. The center of the cell where the protons and neutrons are located
  7. 12. Columns of elements that have something in common
  8. 14. Table showing the all the elements, organized by Atomic number
