Can you explain the answer of this question below:The no. of unpaired ...
Electronic Configuration:
The electronic configuration of the given element is 1s2, 2s2, 3p2. This means that the element has 2 electrons in the 1s orbital, 2 electrons in the 2s orbital, and 2 electrons in the 3p orbital.
Unpaired Electrons:
Unpaired electrons are those electrons that occupy different orbitals and have parallel spins. In the given electronic configuration, the 2 electrons in the 1s orbital and the 2 electrons in the 2s orbital are paired, which means they have opposite spins. However, the 2 electrons in the 3p orbital are unpaired because they have parallel spins.
Answer:
Therefore, the number of unpaired electrons in the given element is 2, and the correct answer is B.
