The total number of electrons is given by adding the numbers as superscripts for each term. This number which is equal to the atomic number Z is found to be 35. The transition elements have Z = 21−30, 39−48, 72−80, 104−112, while the rare earths comprising the Lanthanide series have Z = 57 − 71 and actinides have Z = 89 − 100. Thus the element with Z = 35 does not correspond to either a transition element or a rare earth element.
