Question

Consider the outermost electronic configuration of silicon as follow:

$\left[Ne\right]3s^{2}3p^2$

The given electronic configuration follows:

• A. Aufbau's principle
• B. Paul's rule
• C. Hund's rule
• D. All of the above

Answer 1

The correct option is D All of the above

The given electronic configuration of silicon follows all the given rules. As Aufbau principle explains the energy level filling electrons, Paul's exclusion principle explains the quantum states of filling electrons whereas Hund's rule explains the multipilicity of filled electrons.
