Question

Help? How would you do these? /:
Draw electron dot diagrams for the following:

Na

Mg

As

F

Ne

Answer 1

The elemental symbol stands for the nucleus and all of the electrons EXCEPT the outside shell. Add that as a dot; for example:
Na. [Na is the core + 1 outside e]
Mg: [Mg is the core + 2 outside e]
You get the idea.
