Question

In the periodic table notation below, what information does the number 40.08 tell you? It is the number of protons It is the number of neutrons It is the atomic mass It is the atomic number.

Answer 1

## Step 1In the periodic table, each element is represented by its atomic number and atomic mass. The atomic number is the number of protons in the nucleus of an atom, and it is always an integer. ## Step 2The atomic mass, on the other hand, is the approximate total mass of an atom, including the protons and neutrons. This value is usually not a round number. ## Step 3Given that the number 40.08 in the periodic table is not an integer and is not the atomic number, it is the atomic mass.#
