Isotopes 1

Front

What are isotopes?

Back

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

Front

How do isotopes of an element differ from each other?

Back

Isotopes of an element differ in the number of neutrons they contain.

Front

What is the significance of the number of neutrons in isotopes?

Back

The number of neutrons affects the mass of the isotope and can influence its stability and radioactive properties.

Front

What is the mass number of an isotope?

Back

The mass number of an isotope is the total number of protons and neutrons in its nucleus.

Front

How do you calculate the number of neutrons in an isotope?

Back

To calculate the number of neutrons, subtract the number of protons (atomic number) from the mass number.

Front

What is Potassium-39?

Back

Potassium-39 is an isotope of potassium with 19 protons and 20 neutrons.

Front

If an element has 33 protons, what is its atomic number?

Back

The atomic number of an element is equal to the number of protons, so it is 33.

Front

What is the relationship between isotopes and atomic mass?

Back

The atomic mass of an element is a weighted average of the masses of its isotopes, taking into account their relative abundances.

Front

What does the term 'relative abundance' mean in the context of isotopes?

Back

Relative abundance refers to the proportion of each isotope of an element present in a sample.

Front

How can isotopes be used in scientific research?

Back

Isotopes can be used in various fields such as medicine, archaeology, and environmental science for dating, tracing, and studying processes.
