• # question_answer Total number of electrons in all the p-orbitals of bromine will be A)  5                   B)  7C)   15                             D)  17

Bromine (Atomic number 35), the electronic configuration is $1{{s}^{2}},2{{s}^{2}},2{{p}^{6}},3{{s}^{2}},3{{p}^{6}},4{{s}^{2}},3{{d}^{10}},4{{p}^{5}}$ So, the number of electrons in all -orbitals is 17 here. Hence, the correct option is [d].
