To better understand the concept od mass number, structure of atom is necessary to learn.Definition of mass number The mass number is the sum of the number of protons and neutrons present in the nucleus of an atom of an element. Each proton and neutron has a mass of 1 amu (atomic mass unit). The mass number is represented by symbol A, which comes from the German word “Atomgewicht”, where “wicht” means “weight”. How to calculate the mass number?The mass number can easily be calculated by using th Structure Of Atom, Atomic Mass Unit, Relative Atomic Mass, Mass Number, Number Representation, Chemistry Basics, German Word, Atomic Number, Atomic Structure
