Isotopes Quiz

How many isotopes do common elements usually have?

• None

• Infinite

• Multiple

• One

What is isotopic notation used for?

• Showing the chemical properties of an element

• Representing the number of electrons in an atom's nucleus

• Indicating the atomic mass of an element

• Representing the number of protons and neutrons in an atom's nucleus

What is isotopic abundance?

• The total mass of an isotope in a natural sample

• The number of neutrons in an isotope of an element

• The number of protons in an isotope of an element

• Relative amount of each isotope of an element found in a natural sample

Isotopes have the same number of protons but different number of what?

• atoms

• neutrons

• protons

• electrons

Give an example of an element and its isotopes.

• Carbon - Carbon-12, Carbon-13, Carbon-14

• Oxygen - Oxygen-16, Oxygen-17, Oxygen-18

• Hydrogen - Hydrogen-1, Hydrogen-2, Hydrogen-3

• Nitrogen - Nitrogen-14, Nitrogen-15, Nitrogen-16

How is isotopic abundance calculated?

• By counting the number of protons in a sample

• By measuring the temperature of the sample

• By analyzing the color of the sample

• By measuring the relative amount of each isotope in a given sample.

What is the significance of isotopes in science and industry?

• Isotopes are only used in agriculture, not in science and industry.

• Isotopes have no significance in science and industry.

• Isotopes have various applications in science and industry.

• Isotopes are only used for medical purposes, not in science and industry.

Explain the concept of stable and unstable isotopes.

• Stable isotopes have a stable nucleus and do not undergo radioactive decay, while unstable isotopes have an unstable nucleus and undergo radioactive decay.

• Stable isotopes have a stable nucleus and undergo radioactive decay, while unstable isotopes have an unstable nucleus and do not undergo radioactive decay.

• Stable isotopes have an unstable nucleus and undergo radioactive decay, while unstable isotopes have a stable nucleus and do not undergo radioactive decay.

• Stable isotopes have a stable nucleus and do not undergo radioactive decay, while unstable isotopes have a stable nucleus and undergo radioactive decay.
