How many electrons are in lutetium

A lutetium atom has 71 electrons, arranged in the configuration [Xe] 4f 5d 6s . When entering a chemical reaction, the atom loses its two outermost electrons and the single 5d-electron. The lutetium atom is the smallest among the lanthanide atoms, due to the lanthanide contraction, and as a result lutetium has the highest density, melting point, and hardness of the lanthanides. It is the only lanthanide that cannot use the 4f orbitals for chemistry; thus it is a d-block rather than a… WebThe energy of 4f and 5d electrons are almost close to each other and so 5d orbital remains vacant and the electrons enter into the 4f orbital. Exceptions are in the case of gadolinium, Gd (Z = 64) where the electron enters the 5d orbital due to the presence of half-filled d-orbital and lutetium (Z = 71) enters the 5d orbital.
