What is the basic building block of an atom?

  1. Proton

  2. Neutron

  3. Electron

  4. Quark


Correct Option: A
Explanation:

Protons are the positively charged particles found in the nucleus of an atom, along with neutrons.

What is the process by which an unstable atomic nucleus loses energy and transforms into a more stable nucleus?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: C
Explanation:

Radioactive decay is the process by which an unstable atomic nucleus loses energy and transforms into a more stable nucleus, emitting radiation in the form of particles or electromagnetic waves.

Which type of nuclear reaction involves the combination of two or more atomic nuclei to form a single heavier nucleus?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: B
Explanation:

Nuclear fusion is the process by which two or more atomic nuclei combine to form a single heavier nucleus, releasing a large amount of energy.

What is the term used to describe the splitting of a heavy atomic nucleus into two or more lighter nuclei?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: A
Explanation:

Nuclear fission is the process by which a heavy atomic nucleus splits into two or more lighter nuclei, releasing a large amount of energy.

Which scientist is credited with discovering the neutron?

  1. Albert Einstein

  2. Isaac Newton

  3. James Chadwick

  4. Marie Curie


Correct Option: C
Explanation:

James Chadwick discovered the neutron in 1932, earning him the Nobel Prize in Physics in 1935.

What is the term used to describe the spontaneous emission of particles or electromagnetic radiation from an unstable atomic nucleus?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: C
Explanation:

Radioactive decay is the spontaneous emission of particles or electromagnetic radiation from an unstable atomic nucleus.

Which type of nuclear reaction involves the conversion of one element into another?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: D
Explanation:

Nuclear transmutation is the process by which one element is converted into another, typically through nuclear reactions.

What is the term used to describe the process by which a nucleus captures a neutron and undergoes a transformation?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Neutron Capture


Correct Option: D
Explanation:

Neutron capture is the process by which a nucleus captures a neutron and undergoes a transformation, often resulting in the formation of a new isotope.

Which type of nuclear reaction is used in nuclear power plants to generate electricity?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: A
Explanation:

Nuclear fission is used in nuclear power plants to generate electricity by splitting heavy atomic nuclei into lighter ones, releasing a large amount of energy.

What is the term used to describe the process by which two atomic nuclei collide and exchange particles or energy?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Scattering


Correct Option: D
Explanation:

Nuclear scattering is the process by which two atomic nuclei collide and exchange particles or energy, without undergoing a nuclear reaction.

Which type of nuclear reaction is used in hydrogen bombs to produce a powerful explosion?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: B
Explanation:

Nuclear fusion is used in hydrogen bombs to produce a powerful explosion by combining light atomic nuclei into heavier ones, releasing a large amount of energy.

What is the term used to describe the process by which a nucleus emits an alpha particle?

  1. Alpha Decay

  2. Beta Decay

  3. Gamma Decay

  4. Neutron Emission


Correct Option: A
Explanation:

Alpha decay is the process by which a nucleus emits an alpha particle, which consists of two protons and two neutrons.

Which type of nuclear reaction is used in medical imaging techniques like PET scans?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: C
Explanation:

Radioactive decay is used in medical imaging techniques like PET scans by injecting radioactive isotopes into the body and detecting the emitted radiation.

What is the term used to describe the process by which a nucleus emits a beta particle?

  1. Alpha Decay

  2. Beta Decay

  3. Gamma Decay

  4. Neutron Emission


Correct Option: B
Explanation:

Beta decay is the process by which a nucleus emits a beta particle, which can be either an electron or a positron.

Which type of nuclear reaction is used in carbon dating to determine the age of ancient artifacts?

  1. Nuclear Fission

  2. Nuclear Fusion

  3. Radioactive Decay

  4. Nuclear Transmutation


Correct Option: C
Explanation:

Radioactive decay is used in carbon dating to determine the age of ancient artifacts by measuring the amount of radioactive carbon-14 present in the sample.
