WebbNow, because the atom has 53 electrons, it must also have 53 protons, and to find the number of neutrons we subtract this from the mass number. # n = A – # p = 127 – 53 = … WebbAboutTranscript. Elements are pure substances with specific properties. Atoms are the smallest units of elements that still retain the element's properties. Atoms contain electrons, neutrons, and protons. Each element is defined by the number of protons in its nucleus. Created by Sal Khan.
