Verified step by step guidance1
First, identify the central atom's electron configuration, which is given as 3s^2 3p^3.
Understand that sigma bonds are formed by the overlap of atomic orbitals. In this case, the central atom can use its unpaired electrons to form sigma bonds.
Examine the electron configuration: 3s^2 3p^3. The 3s orbital is fully occupied with 2 electrons, and the 3p orbitals have 3 electrons distributed across them.
Recognize that the 3p orbitals have 3 unpaired electrons, each capable of forming a sigma bond with another atom's orbital.
Conclude that the central atom can form 3 sigma bonds using the 3 unpaired electrons in the 3p orbitals without hybridization.
