Question

Which of these is the part of an atom that contains the protons and neutrons?
electron
orbital
nucleus
shell

Answer 1

The nucleus which is the center of the atom controls the protons and neutrons.

Answer 2

Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus(center) of the atom contains the protons (positively charged) and the neutrons (no charge). The outermost regions of the atom are called electronshells and contain the electrons(negatively charged). So nucleus would be your answer
