What is the Correct Electron Configuration for boron (B)?

Answer: The correct electron configuration for boron (B) is 1s² 2s² 2p¹.

Explanation: The electron configuration represents the arrangement of electrons in the energy levels (shells) and subshells of an atom. Boron, with an atomic number of 5, has five electrons.

According to the Aufbau principle, electrons fill the lowest energy levels first. In boron’s case, the first two electrons occupy the 1s subshell, the next two electrons fill the 2s subshell, and the fifth electron goes into the 2p subshell.

Significance: Understanding boron’s electron configuration helps describe its chemical behavior and its reactivity in chemical reactions. The electron arrangement contributes to its role in various compounds and its position in the periodic table. Read the full article on the electron configuration of boron.
