Question

question 2 (1 point) what is the correct electron configuration for silicon? a) 1s²2s²2p⁶3s⁴ b) 1s²2s²2p⁶2d⁴ c) 1s²2s²2p⁶3s²3p² d) 1s²2s²2p⁶3s¹3p³ e) 1s²2s²1p⁶3s²2p²

Explanation:

Silicon has an atomic number of 14. Electrons fill orbitals in the order 1s, 2s, 2p, 3s, 3p etc. The 1s orbital holds 2 electrons, 2s holds 2, 2p holds 6, 3s holds 2 and 3p holds 2 to make up 14 electrons in total for silicon.

Answer:

C. $1s^{2}2s^{2}2p^{6}3s^{2}3p^{2}$
