What are the three main components of an atomic nucleus?
• Proton • Neutron • Nucleus These components are essential for understanding atomic structure and behavior.
Define nuclear fission.
The process of splitting a heavy atomic nucleus into smaller nuclei, releasing energy Nuclear fission is commonly used in nuclear reactors and atomic bombs.
Define nuclear fusion.
The process of combining light atomic nuclei to form a heavier nucleus, releasing energy Fusion powers the sun and other stars.
What is a nuclear chain reaction?
A series of reactions where the products of one reaction initiate further reactions This is a critical concept in nuclear reactors and weapons.
What is the function of a nuclear reactor?
To initiate and control a sustained nuclear chain reaction Nuclear reactors are used for electricity generation and research.
What element is commonly used as fuel in nuclear reactors?
Uranium Uranium-235 is the isotope most commonly used for fission.
What is a breeder reactor?
A type of nuclear reactor that generates more fissile material than it consumes Breeder reactors can utilize uranium and thorium to produce fuel.
