Practice Problems: Net Charge, Mass Number, Atomic Number

Here’s an atom. What is the atomic number, the mass number and the net charge to this atom? So the atomic number is the number of protons. In this diagram, these little red circles are representing protons here in the nucleus so we’ve got 1, 2, 3, 4, 5 which means my atomic number is […]
