Gcse atomic number
WebThe atomic number counts the number of protons (9); the mass number counts protons + neutrons (19). If there are 9 protons, there must be 10 neutrons for the total to add up to 19. The atomic number is tied to the position of the element in the Periodic Table and therefore the number of protons defines what sort of element you are talking about ... WebYou can use these numbers to calculate the number of protons, neutrons and electrons in an atom. Number of protons = number of electrons = atomic number Number of …
