In the late 1800s, the British scientist J. J. Thomson discovered that atoms were composed of positively-charged and negatively-charged particles. He proposed that these two types of particles were evenly mixed throughout the structure of the atom. How does this atomic model differ from current atomic models?

A. Current atomic models show that atoms do not have positively-charged particles.

B. Current atomic models show an atom's positively-charged particles concentrated in the center of the atom.

C. Current atomic models show that atoms do not have negatively-charged particles.

Carlos · Answer 1

Option B.

Current atomic models show the positive charged particles (protons) concentrated in the center (nucleus) of the atom, along with the neutrons, and the negative charged particles (electrons) distributed around (far from) the nucleus.
