Isotopes

Front

What do isotopes of an element have in common?

Back

Isotopes of an element have the same atomic number but different mass numbers due to varying numbers of neutrons.

Front

What is an isotope?

Back

An isotope is an atom that has the same number of protons but a different number of neutrons compared to other atoms of the same element.

Front

What is the isotopic notation for Carbon-14?

Back

Front

What is the atomic number of an element?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

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

Back

To calculate the number of neutrons, subtract the atomic number from the mass number (Neutrons = Mass Number - Atomic Number).

Front

What is the significance of isotopes in dating methods?

Back

Isotopes, like Carbon-14, are used in radiocarbon dating to determine the age of organic materials.

Front

What is a common use of isotopes in medicine?

Back

Isotopes are used in medical imaging and treatment, such as radioactive iodine in thyroid treatment.
