you know, work on problem 98 from chapter four. In this problem, we're asked eyes about the charge. Nucleus is a positive negative or zero. And the same question for an Adam. So we know that the nucleus is composed of protons and neutrons, so it neutrons are neutral and protons are positively charged. So the nucleus will be positively charged. However, we have Adam's surrounding the nucleus. Excuse me. Electrons surrounding in the nucleus and then Adam. So that means that the electrons outside the nucleus cancel out the effect of the positive charge from the protons. So the atom itself is neutral.
