How many atoms of scandium are in 75 g
WebSep 3, 2024 · Solution. Use the Periodic Table to find the atomic number of Sc ( scandium ). The atomic number is 21, which means that scandium has 21 protons. While a neutral atom for scandium would have the same number of electrons as protons, the ion is shown to have a +3 charge. This means it has 3 fewer electrons than the neutral atom or 21 - 3 = 18 ...
