The ion has 3 9 19 K + A) 18 electrons, 18 protons, 21 neutrons. B) 19 electrons, 18 protons, 20 neutrons. C) 18 electrons, 19 protons, 20 neutrons. D) 19 electrons, 19 protons, 39 neutrons. E) 18 electrons, 19 protons, 19 neutrons

If the mass number is 39, it means that there are 39-19=20 neutrons, 21 for 40-K and 22 for 41K. And the number of electrons is equal to the number of protons, so it's 19 for all isotopes. In the periodic table, you will also see that the most stable isotope has an atomic mass around 39, so the most stable isotope is 39.

Neuropathology and Applied Neurobiology, 39(6) pp. Les PROTONS et les NEUTRONS ont presque la même masse. Ils sont För tusan ! tjugo tusen miljarder grader (2.1013 K) There seem to be about the same numbers of photons, neutrinos, protons, neutrons, electrons (and their antiparticles). 39.

Electrons are negatively charges particles with charge -1 and negligible mass. Potassium's atomic number is 19. Thus, to be electrically neutral, it must have 19 protons and 19 electrons. 39K has 39 - 19 = 20 neutrons. Potassium-39 is composed of 19 protons, 20 neutrons, and 19 electrons. Potassium-40 is composed of 19 protons, 21 neutrons, and 19 electrons.

Here is the generic procedure. Step 1: For the number of protons, it is equal to the atomic number. You can look up the atomic number for any element on the Periodic Table of the Elements, or any Table of the Elements.
