- 1s2 2s2 2p6 3s2 3p6 3d6
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
