Particle A has very little mass in comparison to Particle B. Both particles are in the same atom. Which is the best conclusion about Particles A and B?
A. They have the same charge.
B. They are located in the nucleus together.
C. Particle A has a positive charge, and Particle B is neutral.
D. Particle A orbits the nucleus, and Particle B is located in the nucleus.
Answer (1)
Particle A, being much lighter, is likely an electron that orbits the nucleus, while Particle B, the heavier one, is likely a proton or neutron found in the nucleus. This reflects the standard structure of an atom. Thus, the statement holds true: Particle A orbits the nucleus, and Particle B is located in the nucleus. ;
