How many electrons does NI have? 28 electrons Nickel atoms have 28 electrons and the shell structure is 2.8. 16.2. How do you find the number of atoms? Explanation: Web17 okt. 2012 · For any given element, the number of protons is identical in every atom, but the number of neutrons can vary. Atoms of the same element with different numbers of neutrons are called isotopes. Uranium-235, for example, the key ingredient of nuclear reactor fuel, has 92 protons and 143 neutrons, while the much more abundant uranium …
