What is an isotope?

Back

An isotope is a variant of a chemical element that has the same number of protons but a different number of neutrons.

Front

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

Back

To find the number of neutrons, subtract the atomic number (number of protons) from the mass number (total number of protons and neutrons).

Front

What is the mass number of an isotope?

Back

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

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 isotopes of the same element?

Back

Isotopes of the same element differ in the number of neutrons, which affects their mass.

Front

What is a Bohr model?

Back

A Bohr model is a diagram that represents the arrangement of electrons in an atom, showing energy levels.

Front

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

Back

The number of neutrons affects the stability and radioactive properties of an isotope.
