Explain how you would create a Lewis dot diagram for the following: (1 mark each, 4 marks total) Example: When creating a Lewis Dot diagram for carbon I would look at the periodic table of elements and find that the atomic number is 6. Then I would draw the C. I know that two electrons would go in the first orbit. That leaves 4 electrons in the valence shell. So, the Lewis Dot diagram would look like a C with four dots around it.

a) phosphorus atom

b) chlorine ion

c) beryllium atom

d) calcium ion
