✔In this presentation, you will learn more on what an atom is, what the subatomic particles are. Those are neutrons, protons, and electrons. Additionally, we are looking at the term isotopes and how they occur or are used in real life. Nitrogen is the atom used for a vivid example. We also touch on such terms as orbitals and radioactive atoms.✔ Here is a YouTube link, MAKE SURE TO WATCH IT :)) ➡➡➡https://www.youtube.com/watch?v=n7iKblrxCrg Here is a Facebook post on a LabGirl page: ➡➡➡ https://www.facebook.com/labgirldzd/

8. Nitrogen
14 - mass of the atom. #p+#n

Average of different types of N
