Isotopes

Front

What are isotopes?

Back

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

How do carbon-12 and carbon-14 differ?

Back

Carbon-12 has 6 neutrons, while carbon-14 has 8 neutrons. They both have 6 protons.

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

What is mass number?

Back

Mass number is the total number of protons and neutrons in an atom's nucleus.

Front

How many protons does carbon have?

Back

Carbon has 6 protons.

Front

What is the mass number of carbon-13?

Back

The mass number of carbon-13 is 13.

Front

How many neutrons are in carbon-12?

Back

Carbon-12 has 6 neutrons.

Front

What is the relationship between isotopes and chemical properties?

Back

Isotopes of an element have the same chemical properties because they have the same number of protons and electrons.

Front

What is the significance of isotopes in dating materials?

Back

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

Front

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

Back

Number of neutrons = Mass number - Atomic number.
