In some atoms like nitrogen, oxygen, etc the number of electrons, protons, and neutrons are the same. It is not necessary that the number of neutrons is the same as the number of protons or electrons. Therefore, there are 18 neutrons in the chlorine atom. We have to take the difference of atomic mass and number of protons or electrons, this will give the number of neutrons.

Now to find the number of neutrons in the atom we should know the atomic mass of the chlorine atom and the atomic mass of the chlorine atom 35. So, the number of protons will also be 17. Chlorine is an element with unique properties Chlorine has an atomic number of 17 and an atomic mass of 35.45, meaning that an atom of chlorine consists of 17 protons, 17 electrons, and 18 neutrons. Since in an electrically neutral chlorine atom the number of protons will be the same as the number of electrons. This means that there are 17 electrons in the chlorine atom. Note: It is not necessary that the number of neutrons is the same as the number of protons or electrons. State the number of protons, electrons, and neutrons in the following isotopes: 35Cl17, 37Cl. Those that have a negative charge and revolve around the nucleus are electrons, those who have a positive charge and remain in the nucleus are protons, and those who do not have a charge and remain in the nucleus are neutrons.Ĭhlorine is the element of group 17 of the p-block and its atomic number is 17. Therefore, there are 18 neutrons in the chlorine atom. Thus, since the atomic mass of iron is 55.847 amu, one mole of iron. Chlorine is an Element of Atomic Number 17. Calcular los protones, electrones y neutrones. So, first, find the atomic number which will tell the number of electrons, and protons in the atom and then take the difference of atomic mass and number of protons or electrons, this will give the number of neutrons.Īs we know that in an atom there are mainly three components: electrons, protons, and neutrons. Puedes encontrar el número de protones, neutrones y electrones de un átomo de manera sencilla utilizando información de la tabla periódica. Hint: The number of neutrons can be found by the atomic mass of the element. Two decay chains comprising seven -decays and a spontaneous fission.
