The correct ground state electron configuration of boron,which has 5 electrons,is A) 1s²2s²2p. B) 1s²2s²2p³. C) 1s²1p²2s. D) 1s²2p²3s. E) 1s²2p³.

Question

Quizplus · Accepted Answer

The correct ground state electron configuration for boron, which has 5 electrons, is represented by option A, which translates to "1s^2 2s^2 2p^1" in conventional notation. This configuration shows that boron has two electrons in the 1s orbital, two in the 2s orbital, and one in the 2p orbital, totaling five electrons.
