Web21 dec. 2015 · A. the number of neutrons in a nucleus B. the total number of neutrons and protons in a nucleus C. the number of protons in a neutral atom D. the number of atoms in 1 g of an element Slide 4 2. Who is responsible for discovering the neutron? A. Rutherford B. Chadwick C. Thomson D. None of the above Slide 5 2. WebThe total number of protons and neutrons in an atom is called its mass number (A). The number of neutrons is therefore the difference between the mass number and the atomic number: A – Z = number of neutrons. atomic number ( Z) = number of protons mass number ( A) = number of protons + number of neutrons A − Z = number of neutrons
