Matter Exam Question 2

The video tutorial explains the structure of a nitrogen atom, including its nucleus, protons, neutrons, and electrons. It guides students through labeling a diagram and understanding the charges of different particles. The tutorial also covers calculating the mass number of an atom by adding protons and neutrons. Finally, it discusses the electronic structure of an oxygen atom, helping students identify the correct diagram based on the atomic number and electron distribution.

Explain why certain diagrams can be eliminated when identifying the electronic structure of an oxygen atom.

Describe the electronic structure of an oxygen atom based on the information provided.
