  5. The atomic mass will be displayed in the "Atomic Mass" field.

Understanding Atomic Mass

The atomic mass of an element is the total number of protons and neutrons in the nucleus of an atom. Electrons are not included in the atomic mass calculation because they have a negligible mass compared to protons and neutrons.

Formula

Atomic Mass = Number of Protons + Number of Neutrons
