Isotopes

Front

What is an isotope?

Back

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

Front

What is the atomic mass of an isotope?

Back

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

Front

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

Back

Subtract the atomic number (number of protons) from the atomic mass.

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

Do isotopes of the same element have the same chemical properties?

Back

Yes, isotopes of the same element have the same chemical properties because they have the same number of protons and electrons.

Front

What is the difference between Carbon-12 and Carbon-14?

Back

Carbon-12 has 6 neutrons, while Carbon-14 has 8 neutrons.

Front

What happens to the atomic number when an element becomes an isotope?

Back

The atomic number remains the same when an element becomes an isotope.

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 many protons does Carbon have?

Back

Carbon has 6 protons.

Front

What is the formula to calculate atomic mass?

Back

Atomic mass = Number of protons + Number of neutrons.
