How many electrons does a neutral potassium atom have? A. 0 B. 17 C. 19 D. More information is needed to figure this out.
Weegy: In a neutral potassium atom it has C. [ 19 electrons Use the Periodic Table to get Atomic number (19), and atomic mass (39.1). The atomic number is the number of protons, and in the neutral atom, also the number of electrons: 19. The atomic mass is the sum of the mass of the protons and neutrons, 39.1. Subtract the number of protons (use integers) from the atomic mass, 39 - 19 = 20, which is the number of neutrons. Protons = 19 Neutrons = 20 Electrons = 19 reference: ] (More)
