Number of protons of he
WebThat's the number of protons. So we've got a 19 right here to calculate the number of neutrons we take. Our mass number minus are atomic number or often a minus C. In this case, I've got 40 minus 19. And the answer is 21 neutrons. Our next problem is for this substance radium 2 22 and 88 Remember, are lower number is our number of protons.
