Electrons travel in definite circular pathways around the nucleus. C a core of protons and neutrons surrounded by electrons. It is the negatively charged part of the atom.
Indicate whether each of the following statements about the nucleus of an atom is true or false. The protons are positively charged which gives the nucleus a positive charge while the neutrons have no charge. Not significant to the overall mass of the atom.
