Informally, Atomic Mass is the number of protons and neutrons. Formally, atomic mass is normalized to the mass of Carbon-12, because the mass of the proton and the mass of the neutron are not exactly equal.
What else can I help you with?
How do you define the atomic mass of an element?
The total mass of the atom. In other words the total mass of the protons and neutrons of an atom
What isotope defines the atomic mass unit?
Carbon-12 isotope is used to define the atomic mass unit, which is equal to 1/12th of the mass of a carbon-12 atom.
What does the atomic weight mass number of an element represent?
The atomic weight, or atomic mass, of an element represents the average mass of its isotopes, weighted by their natural abundance. It is typically expressed in atomic mass units (amu) and reflects the total number of protons and neutrons in the atomic nucleus, which collectively define the mass number. While the mass number is a whole number indicating the total count of protons and neutrons in a specific isotope, the atomic weight accounts for the relative proportions of all isotopes of the element found in nature.
How are atomic number and atomic mass related to atomic structure?
The atomic number tells how many protons are in the atom, and the atomic mass tells how many neutrons and protons are in the atom together. Like Oxygen has an atomic number of 8. It also has 8 protons. It's atomic mass is 16. It also has 16 neutrons and protons. Helium's atomic number is 1. It only has 1 proton. It's atomic mass is 1 because it doesn't have any neutrons.
The mass of an atom usually expressed in atomic mass units is its?

atomic weight
One twelfth the mass of a carbon 12 atom is used to define an?
One twelfth the mass of a carbon 12 atom is used to define an atomic mass unit (amu) or unified atomic mass unit (u). This unit is used to express atomic and molecular weights on a scale relative to the mass of a carbon-12 atom, making it a common reference point in chemistry.
How do you define the atomic mass of an element?
The total mass of the atom. In other words the total mass of the protons and neutrons of an atom
