3. O-16 and O-18 atoms are isotopes. Which is correct?

  • They have different numbers of neutrons
  • They have different electron configurations
  • They have different atomic numbers
  • They have the structure 1s2 2s2 2p6 3s2 3p4

4. What is the trend in ionisation energy down a group?

  • It varies (proton and repulsion effect depends on the element)
  • It increases up to the fourth element then decreases
  • It decreases (more quantum shells)
  • It increases (more protons)

5. How many electrons can fit on the 2nd quantum shell? Which orbitals does it contain?

  • 10; the s (1x2) and p (2x4) orbitals
  • 8 ; the s (1x2) and p (3x2) orbitals
  • 6; the p(3x2) orbitals
  • 18; the s (1x2) p (3X2) and d (5x2) orbitals
