Telling the teacher about a chemical spill immediately
Explanation:
In a Lewis dot diagram, the electrons are arranged so that, when full, two electrons placed beside each other are on four sides of the element symbol.
An electron is 3-dimensional, so you can start on any side on a 2D diagram.
Continue this pattern depending on how many electrons you have:
When adding an electron after the first, it is placed on the next side going either counterclockwise or clockwise. Which ever direction you choose, be consistent.
After the fourth electron, so that one electron is on each side, place a dot beside your first electron and continue the pattern.
