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, resulting in different mass numbers.

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

Number of Neutrons = Mass Number - Atomic Number.

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 the difference between atomic mass and mass number?

Back

Atomic mass is the weighted average mass of an element's isotopes, while mass number is the total count of protons and neutrons in a specific isotope.
