Question

Rutherford made the same inferences. He concluded that all of the positive charge and virtually all of the mass of an atom are concentrated in one tiny area and the rest of the atom is mostly empty space. Rutherford called the area of concentrated positive charge the nucleus. He predicted-and soon discovered-that the nucleus contains positively charged particles, which he named protons. Rutherford also predicted the existence of neutral nuclear particles called neutrons, but he failed to find them. However, his student James Chadwick discovered them several years later.

What did Rutherford predict was also in the nucleus?
A. Protons.
B. Electrons
C.neutrons

Answer 1

Rutherford predicted the presence of neutrons in the nucleus along with protons. This prediction was later confirmed by James Chadwick's discovery in 1932.

Step-by-step explanation:

Rutherford predicted that neutrons were also present in the nucleus. He reasoned that if the nucleus only contained positively charged protons, the repulsive forces between protons would cause the nucleus to break apart. To keep the atom electrically neutral, a neutral particle was needed in the nucleus. It was not until 1932 that James Chadwick discovered the neutrons.
