no work on problem 44 from chapter four. In this problem, we're asked to explain why atoms are neutral electronically speaking electrically speak. So the reason that Adams or neutral is because they have an equal number of protons and electrons. So we have electrons surrounding this positively charged nucleus with protons. It and the number of electrons that are surrounding it is equal to the protons number of protons in the nucleus. So be positive charge. Inside the nucleus is neutralized by the same number of electrons surrounding nucleus, making the Adam.
