Atomic Structure Quiz

What is the definition of isotopes?

• Isotopes are identical atoms with the same mass number.

• Isotopes are compounds formed by different elements.

• Isotopes are variants of a chemical element with the same number of protons but different numbers of neutrons.

• Isotopes are elements with different numbers of protons.

What are the two main types of isotopes?

• Stable isotopes and radioactive isotopes

• Natural isotopes and artificial isotopes

• Heavy isotopes and light isotopes

• Chemical isotopes and physical isotopes

List one application of isotopes in industry.

• Radiography in non-destructive testing

• Isotopes for water purification

• Isotopes in solar panel manufacturing

• Isotopes in food preservation

What does isotope notation typically include?

• Element symbol, mass number, and atomic number.

• Element name, charge, and electron configuration.

• Atomic number, element group, and density.

• Mass number, element name, and neutron count.

How do stable isotopes differ from unstable isotopes?

• Stable isotopes can decay under certain conditions, unlike unstable isotopes.

• Unstable isotopes are found only in nature, while stable isotopes are man-made.

• Stable isotopes are always heavier than unstable isotopes.

• Stable isotopes are non-radioactive and do not decay, while unstable isotopes are radioactive and decay over time.

Name a medical application of isotopes.

• Isotopes in physical therapy treatments.

• Medical imaging using radioactive isotopes in PET scans.

• Using isotopes for blood transfusions.

• Isotopes for dental fillings.

What is the significance of isotopes in carbon dating?

• Isotopes, particularly Carbon-14, are crucial for determining the age of organic materials in carbon dating.

• Isotopes have no impact on the dating of fossils.

• Carbon dating relies solely on Oxygen-16 isotopes.

• Isotopes are only used in nuclear power generation.

How can isotopes be used in tracing environmental changes?

• Isotopes provide real-time data on current weather patterns.

• Isotopes can only be used in medical applications, not environmental studies.

• Isotopes are used to predict future environmental disasters.

• Isotopes help trace environmental changes by analyzing stable isotope ratios in environmental samples to reconstruct past climate conditions.

What role do isotopes play in nuclear medicine?

• Isotopes are primarily used for food preservation techniques.

• Isotopes have no significance in medical applications.

• Isotopes are only used for research purposes in laboratories.

• Isotopes are used in nuclear medicine for diagnosis and treatment, particularly in imaging and targeted therapies.

Explain how isotopes can be used in radiation therapy.

• Isotopes are primarily used in agriculture to improve crop yields.

• Isotopes are used to enhance the taste of food during cooking.

• Isotopes are used in radiation therapy to create a protective shield around healthy cells.

• Isotopes are used in radiation therapy to emit radiation that targets and destroys cancer cells.
