Activity 3- Subatomic Particles Diagram Directions. The structure below shows an atom of oxygen with 8 electrons represented by (-) and 8 protons represented by (+) and neutrons with no charge. Draw a similar structure from above basing your drawing on the atom's number of protons, neutrons and electrons. Name of atoms 1. Beryllium 2. Aluminum 3. Nitrogen 4. Sulfur 5.
