Across
  1. 3. Has one valence electron, its energy level is n=1
  2. 4. has 4 valence electrons, atomic number is 14
  3. 6. would lose 3 electrons and become a cation. Would have the smallest ionic radii
  4. 9. 15 protons, 16 neutrons, and 15 electrons
  5. 11. out of the alkali earth metals it has the smallest atomic radius
  6. 13. Halogen with 17 electrons
  7. 14. has a mass of 14.01, 7 protons, 7 neutrons, and 7 electrons
  8. 15. Atomic number 16, 16 protons, p block
  9. 16. has a bigger atomic radius than be and a smaller atomic radius of ca and is an alkaline metal
  10. 17. a halogen, non-metal and has a charge of -1
Down
  1. 1. would have the highest electronegativity in the carbon group. (its the most common element in the universe.)
  2. 2. Highest electro-negative in the noble gases group(used in light signs)
  3. 3. has the highest ionization energy(often used to fill up balloons so they'll float)
  4. 5. 18 protons, 18 electrons, and p block
  5. 7. Has six valence electrons(One of the main things we breathe)
  6. 8. has a atomic radius between
  7. 10. 11 protons, 12 neutrons, 11 electrons, 22.990 atomic mass
  8. 12. metal, 13 electrons, P block (one of the most abundant metals in the earth’s crust)
