WebJun 8, 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). WebThe mass number (symbol A, from the German word Atomgewicht [atomic weight]), [1] also called atomic mass number or nucleon number, is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus. It is approximately equal to the atomic (also known as isotopic) mass of the atom expressed in atomic mass units.

WebApr 8, 2014 · In order for the atom to remain electrically neutral the protons and electrons must balance each other. Two examples would be Sodium (Na) and Chlorine (Cl) Sodium has an atomic number of 11 and an amu of 23 Sodium has 11 protons 12 neutrons and 11 electrons. 11 protons - atomic number 11 11 + 12 = 23 the amu 11+ = 11− WebIn an atom the number of protons and electrons are equal.
