Vedclass · Answer

(B) For the neutral atom ${ }_{71}^{175} Lu$:The atomic number $(Z)$ is $71$,which represents the number of protons $(p^+)$.Since the atom is neutral,the number of electrons $(e^-)$ is equal to the number of protons,so $e^- = 71$.The mass number $(A)$ is $175$. The number of neutrons $(n^0)$ is calculated as $A - Z = 175 - 71 = 104$.Therefore,the number of protons,neutrons,and electrons are $71, 104$,and $71$ respectively.

The number of protons,neutrons and electrons in ${ }_{71}^{175} Lu$,respectively,are:
