For which discovery in 1932 was James Chadwick best known?

Correct option is C

The correct answer is (c) Neutron

• In 1932, James Chadwick discovered the neutron, a neutral subatomic particle located in the nucleus of an atom.

• This discovery was critical in explaining the atomic mass of elements and understanding nuclear reactions, including nuclear fission.

• Before Chadwick’s discovery, the atom was thought to consist only of protons and electrons.

• Neutrons helped explain why atoms of the same element could have different masses (isotopes).

Information Booster:
• Neutrons are uncharged particles with mass slightly greater than that of protons.
• Neutron discovery enabled advancements in nuclear physics and atomic bombs.
• Chadwick was awarded the Nobel Prize in Physics in 1935 for this discovery.
• The discovery completed the modern picture of the atomic nucleus.
• Neutrons are key in chain reactions in nuclear reactors.
• Neutron number determines the isotope of an element.
