  2. 3. Positive Ion
  3. 7. Negative Ions
  4. 8. series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium.
  5. 10. helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn).
  6. 12. is a type of chemical element which has a preponderance of properties in between, or that are a mixture of, those of metals and nonmetals.
Down
  1. 1. The metallic elements in the periodic table located between the transition metals and the weakly nonmetallic metalloids.
  2. 4. have a diverse range of individual physical and chemical properties.
  3. 5. Neutral Ion
  4. 6. In actual practice, the f-block lanthanide and actinide series are also considered transition metals and are called "inner transition metals".
  5. 9. consist of the chemical elements lithium (Li), sodium (Na), potassium (K), rubidium (Rb), caesium (Cs), and francium (Fr).
  6. 11. series of chemical elements comprises the 15 metallic chemical elements with atomic numbers 57–71, from lanthanum through lutetium.
