Answer 1

QUESTION -

What is atomic mass number ?

ANSWER -

Definition :-

Atomic mass number is defined as the number of times of a given atom is heavier than 1/12 of the mass of one atom of C12.

✔️ mass of proton +mass of neutron = atomic mass number

Noteworthy point :-

It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.

Answer:

• A property closely related to an atom's mass number is its atomic mass.
• The atomic mass of a single atom is simply its total mass and is typically expressed in atomic mass units or amu.
• By definition, an atom of carbon with six neutrons, carbon-12, has an atomic mass of 12 amu.
