MHT CET 2024 Chemistry question
What is the total number of unpaired electrons in an element placed at period-4 and group-12 either in excited or at ground state?
Answer: (A)
Solution
The element in period 4 and group 12 is zinc, , with ground-state configuration . Both the subshell (10 electrons) and the orbital (2 electrons) are completely filled, so all electrons are paired and the number of unpaired electrons is zero (zinc is diamagnetic, which is
