How many neutrons does lutetium have
WebIn this case, hydrogen (H) has an atomic number of 1 and, therefore, every atom of hydrogen will contain 1 proton. The equation shown above can then be applied, as follows. Mass Number = # of Protons + # of Neutrons. Mass Number = 1 + 2. Therefore, this particular atom of hydrogen will have a mass number of 3. WebHow many valence electrons does scandium (Sc) have. Valency is determined from the electron configuration of the element in the excited state. The electron configuration of scandium excited state is Sc* (21) = 1s 2 2s 2 2p 6 3s 2 3p 6 3d 1 4s 1 4p x1. Here, scandium has three unpaired electrons.
