How do you determine the mass number of an atom?

Back

The mass number is determined by adding the number of protons and neutrons in the nucleus of an atom.

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.

What is the significance of the electron configuration in a Bohr model?

Back

The electron configuration in a Bohr model indicates the arrangement of electrons in the energy levels around the nucleus, which affects the atom's chemical properties.

How many electrons can the first energy level hold in a Bohr model?

Back

The first energy level can hold a maximum of 2 electrons.

Front

What is the maximum number of electrons that can be held in the second energy level?

Back

The second energy level can hold a maximum of 8 electrons.
