Splet17. jan. 2024 · Given an atomic number (Z) and mass number (A), you can find the number of protons, neutrons, and electrons in a neutral atom. For example, a lithium atom (Z=3, A=7 amu) contains three protons (found from Z), three electrons (as the number of protons is equal to the number of electrons in an atom), and four neutrons (7 – 3 = 4). Splet20. jun. 2024 · Mass number is nearly equal to atomic mass of an element. Mass number is a whole number while atomic number occurs in decimals except in the case of carbon-12, which has the exact atomic mass of 12 u. Mass number is a dimensionless quantity while atomic mass is expressed in the atomic mass unit (amu or u).
Splet22. dec. 2024 · Brainly User Answer: A property closely related to an atom's mass number is its atomic mass.
