Lithium amount of protons
Web18 jan. 2016 · Neutral elements must have the same number of protons as electrons, because an imbalance would not cancel out all charges. Lithium has an atomic number Z of 3, so by definition, it has 3 protons. Hence, neutral lithium atoms must contain 3 … WebThere are 11 protons in a sodium atom but only 3 in a lithium atom, so the nuclear charge is much greater. You might have expected a much larger ionization energy in sodium, …
