What did Rutherford do that was such a big improvement on JJ’s blueberry muffin atomic model?
What two things did Bohr’s model do that Rutherford’s did not?
Where are protons, neutrons, and electrons found in the Bohr model of the atom?
Write each subatomic particle. Label them with their mass, charge, and where they are located in the atom (according to the Bohr model).
How many protons are in magnesium?
An isotope of carbon has a mass of 13amu. How many neutrons does it have?
What is the mass of the most common isotope of gold?
