The ground state electronic configuration for silicon is 1s²2s²2p⁶3s²3p².Which of the following elements would be expected to be chemically similar to silicon? A)boron with configuration 1s²2s²2p¹ B)lithium with configuration 1s²2s¹ C)carbon with configuration 1s²2s²2p² D)sodium with configuration 1s²2s²2p⁶3s¹

Question

Quizplus · Accepted Answer

Elements with similar chemical properties have similar electron configurations. Silicon and carbon have the same outer electron configuration of 3s²3p², making them chemically similar to each other. Neither boron nor sodium have the same electron configuration as silicon, so they are not chemically similar to it. Lithium has a much simpler electron configuration and is not expected to be chemically similar to silicon. Therefore, the best choice is option C, carbon, which has the same outer electron configuration as silicon.
