Exploring the Neutron Discovery

What are the key properties of a neutron?

• Neutrons are positively charged particles found in the nucleus.

• Neutrons have a mass of approximately 9.11 x 10^-31 kg.

• Neutrons are neutral particles with a mass of approximately 1.675 x 10^-27 kg, found in atomic nuclei.

• Neutrons are found in the electron cloud surrounding the nucleus.

How does the mass of a neutron compare to that of a proton?

• A neutron is slightly heavier than a proton.

• A neutron has the same mass as a proton.

• A neutron is much heavier than a proton.

• A neutron is lighter than a proton.

Who is credited with the discovery of the neutron and in what year?

• James Chadwick, 1932

• Ernest Rutherford, 1920

• Albert Einstein, 1930

• Niels Bohr, 1935

What role do neutrons play in the stability of an atomic nucleus?

• Neutrons increase the energy levels of electrons in an atom.

• Neutrons are responsible for the chemical properties of an atom.

• Neutrons are the primary carriers of electric charge in the nucleus.

• Neutrons help stabilize the nucleus by providing strong nuclear force that counteracts proton repulsion.

How did the discovery of the neutron change the understanding of atomic structure?

• Neutrons were found to be responsible for chemical bonding between atoms.

• The neutron was discovered to be a charged particle in the nucleus.

• The discovery of the neutron proved that atoms are indivisible and unchangeable.

• The discovery of the neutron led to the understanding that atomic nuclei are made of protons and neutrons, explaining isotopes and nuclear stability.
