Nuclear reactions

What is nuclear fission?

• A process where two light nuclei combine to form a heavier nucleus, releasing energy.

• A nuclear reaction where a heavy nucleus splits into two lighter nuclei, releasing energy.

• A method of generating electricity using solar panels.

• A chemical reaction that occurs in the presence of oxygen, producing heat and light.

What is an isotope?

• An atom with the same number of protons but a different number of neutrons.

• An atom with a different number of protons and the same number of neutrons.

• An atom that has lost or gained electrons.

• An atom with the same number of protons and neutrons.

What is the significance of the sun in nuclear reactions?

• The sun is a natural reactor where nuclear fusion occurs, providing energy to the solar system.

• The sun is primarily a source of chemical energy for plants.

• The sun's energy is generated through radioactive decay processes.

• The sun has no significant role in nuclear reactions.

What is the role of neutrons in an atom?

• Neutrons help stabilize the nucleus and contribute to the atomic mass.

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

• Neutrons determine the charge of the atom.

• Neutrons are involved in the formation of chemical bonds.

What is the atomic number?

• The number of neutrons in the nucleus of an atom.

• The number of protons in the nucleus of an atom, which determines the element.

• The total number of electrons in an atom.

• The mass of an atom measured in atomic mass units.

What is a disadvantage of nuclear energy?

• It leaves behind radioactive waste.

• It produces greenhouse gas emissions.

• It is a renewable energy source.

• It requires no safety measures.

What is a key advantage of nuclear fusion compared to nuclear fission?

• Nuclear fusion produces more energy than nuclear fission.

• Nuclear fusion is easier to control than nuclear fission.

• Nuclear fusion generates more radioactive waste than nuclear fission.

• Nuclear fusion is less expensive to implement than nuclear fission.

What is radioactive waste?

• Material that is radioactive and remains hazardous to health and the environment.

• A type of waste that is safe to dispose of in regular landfills.

• Waste that can be recycled and reused without any hazards.

• Non-radioactive materials that are discarded after use.

What is a proton?

• A negatively charged particle found in the nucleus of an atom.

• A positively charged particle found in the nucleus of an atom.

• A neutral particle found in the nucleus of an atom.

• A positively charged particle that orbits the nucleus of an atom.

Which particle is not part of an atom's nucleus?

• Proton

• Neutron

• Electron

• Quark
