How many electrons in the first 20 elements
WebMar 6, 2024 · For example, Ca 2+ has a +2 charge so it has lost 2 electrons from the neutral state. Calcium’s atomic number is 20, therefore the ion has 18 electrons. 3 Add the charge to the atomic number for negative ions. When an ion has a negative charge, the atom has gained electrons. WebJul 28, 2024 · The 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).
