500
Explain how to find the number of protons and electrons in any element. Name the relationship of electrons to protons ( <,>,=).
What is by looking at the atomic number of the element? What is they are equal?
500
Explain how to find the number of neutrons in any element and why this works.
What is "bottom minus top" or subtract the atomic number from the atomic weight? (This works because electrons have little to no weight, therefore the atomic weight is made up of the protons and neutrons. Because you already know the number of protons, you can subtract it from the atomic weight leaving you with the number of neutrons).
