These are the steps for how to draw an electron dot diagram
What is:
1. determine the group number of the element
2. use the ones column (place value) to determine the number of valence electrons
3. write the chemical symbol and add the number of dots around the symbol
4. if there aren't 8 electrons, the atom is unstable (unless hydrogen or helium)
5. any unpaired electron tells how many bonds the atom can make
