2. When does the 4p orbital begin to fill?

  • after the 3d orbital is full
  • after the 4s sub-shell is full
  • before the 3d orbital is full
  • after the 4s orbital is full

3. The Periodic Table is structured in blocks of 2,6,10 and 14 elements, linked to....

  • sub-shells
  • atoms
  • orbitals
  • shells

4. What affect does the principal quantum number n, have on the energy level and distance of the shell from the nucleus?

  • the principal quantum number has no affect on the energy level or distance of the shell from the nucleus
  • the larger the value of the principal quantum number, the higher the energy level and the closer the shell is to the nucleus
  • the larger the value of the principal quantum number , the higher the energy level and the further the shell from the nucleus
  • the larger the value of the principal quantum, the lower the energy level and the closer the shell is to the nucleus

5. When positive ions are formed, what happens to the electrons in the highest energy orbitals?

  • the number of electrons stays the same
  • the number of the electrons is doubled
  • electrons are removed
  • electrons are added
