What is the definition of isotopes?
Isotopes are atoms that have the same mass but different chemical properties.
Isotopes are elements that can only exist in gaseous form.
Isotopes are elements with different numbers of protons.
Isotopes are variants of a chemical element with the same number of protons but different numbers of neutrons.
How do isotopes of the same element differ?
Isotopes differ in the number of protons.
Isotopes have different chemical properties.
Isotopes vary in their atomic mass due to electron differences.
Isotopes differ in the number of neutrons.
What are the two main types of isotopes?

What is a radioactive isotope?
A radioactive isotope is an unstable atom that emits radiation during its decay.
A radioactive isotope is an atom that absorbs radiation from its surroundings.
A radioactive isotope is a type of chemical bond between atoms.
A radioactive isotope is a stable atom that does not emit radiation.
What is the significance of isotopes in carbon dating?
Isotopes are significant in carbon dating because Carbon-14's decay rate allows for accurate age estimation of organic materials.
Isotopes only affect the color of organic materials.
Isotopes are irrelevant in carbon dating.
Carbon-14 is the only isotope used in dating rocks.
How are isotopes used in medical imaging?
Isotopes are used in construction to measure building materials.
Isotopes are primarily used in agriculture to improve crop yields.
Isotopes are used in medical imaging to create images of the body's internal structures by emitting radiation that is detected by imaging devices.
Isotopes are used to enhance the taste of food during cooking.
What role do isotopes play in nuclear medicine?
Isotopes are primarily used for food preservation.
Isotopes have no application in medical treatments.
Isotopes are used in nuclear medicine for diagnosis and treatment through imaging and targeted therapies.
Isotopes are only used in research laboratories.
What is the difference between stable and unstable isotopes?
Stable isotopes are always heavier than unstable isotopes.
Unstable isotopes are found only in nature, while stable isotopes are man-made.
Stable isotopes can be radioactive under certain conditions.
Stable isotopes do not decay, whereas unstable isotopes are radioactive and decay.
How can isotopes be used in cancer treatment?
Isotopes are used to enhance the taste of food.
Isotopes are used in cancer treatment to increase appetite.

What is the concept of isotopic abundance?
Isotopic abundance refers to the total mass of an element in a sample.
Isotopic abundance is the relative proportion of different isotopes of an element in a sample.
Isotopic abundance is the measure of the energy levels of isotopes.
Isotopic abundance indicates the temperature at which an element melts.
How do isotopes affect the atomic mass of an element?
Isotopes do not affect atomic mass at all.
Isotopes affect the atomic mass by contributing to a weighted average based on their relative abundances.
Isotopes are irrelevant to the concept of atomic mass.
Isotopes only increase the atomic mass of an element.
