From the Peri How many neutrons are present in an atom of K that has mass number = 39? mass number = number of protons + number of neutrons number of neutrons = = = change Isotopes • Not all atoms of the same element contain the same number of _____ (remember number of protons determines the identity of elements, NOT the number of neutrons). Definition 2018-06-16 Subatomic Particles: Electrons, Protons, and Neutrons Therefore, for K: 19 protons = _____ electrons in a neutral atom. Chemistry 11 – Atomic Theory Study Guide 2 How many neutrons are present in an atom of K that has mass number = 39?
