The Atomic Mass of an element includes the total mass of its protons, neutrons, and electrons, though the contribution of electrons is negligible due to their very small mass compared to protons and neutrons. It is primarily determined by the number of protons and neutrons in the nucleus, which collectively are referred to as nucleons. Atomic mass is typically expressed in atomic mass units (amu) and reflects the weighted average of the masses of an element's isotopes based on their natural abundance.
What else can I help you with?
An element's atomic mass does not include the mass of its?
An element's atomic mass does not include the mass of its electrons. Electrons have such a small mass compared to protons and neutrons that they are not typically included in calculations of atomic mass.
What is the atomic mass number of an isotope that it has an atomic number of five and include six neutrons?
It is 11.009
What element has a smaller atomic mass than krypton?
Argon (Ar) has a smaller atomic mass than krypton (Kr). Krypton has an atomic mass of about 83.80 u, while argon has an atomic mass of approximately 39.95 u. Other elements with smaller atomic masses than krypton include neon (Ne) and helium (He).
Why don't he include the electron in atoms mass?
when compared to the mass of protons and neutrons, the mass of the electrons is negligible and hence not included in atomic mass.
How do you figure the atomic mass of element when you have electrons?
The term atomic mass is used only for isotopes; for chemical elements the term atomic weight is recommended.But atomic masses and atomic weights include also all electrons.
An element's atomic mass does not include the mass of its?
An element's atomic mass does not include the mass of its electrons. Electrons have such a small mass compared to protons and neutrons that they are not typically included in calculations of atomic mass.
What is the atomic mass number of an isotope that has an atomic number of five and include 6 neutrons?
Mass number = 5 + 6 = 11
What is the general relationship between atomic number and atomic mass weight?
As atomic number rises so does the atomic mass. There is no close relationship. Atomic number is the number of protons in the nucleus. Average atomic mass takes the mass of naturally occurrring isotopes which include the mass of the varying numbers of neutrons present which account for a large proportion of the overall mass of an atom.

What is bigger the atomic mass or atomic number?
Atomic no.=no. of protons Atomic mass=no. of protons+no. of neutrons Hence, atomic mass is greater
What is the atomic mass-?
The atomic mass is the mass of a molecule, atomic particle or sub-atomic particle.
The mass of an atom usually expressed in atomic mass units is its?
Atomic mass
