Web29 dec. 2024 · So, the atomic number for Iodine is 53, hence, the number of protons in the Iodine atom is also 53. Now, to determine the number of neutrons in an atom, use this formula. ⇒ Number of neutrons in atom = Atomic mass of the atom (rounded to the nearest whole number) – Number of proton in an atom WebThe atomic number of iodine (53) tells us that a neutral iodine atom contains 53 protons in its nucleus and 53 electrons outside its nucleus. Because the sum of the numbers of protons and neutrons equals the mass number, 127, the number of neutrons is 74 (127 – 53 = 74). Since the iodine is added as a 1- anion, the number of electrons is 54 ... how does dermatitis scalp look like https://theuniqueboutiqueuk.com
