which is the electron configuration for boron?\no $1s^{2}2s^{3}$\no $1s^{2}2s^{2}3s^{1}$\no $1s^{1}2s^{2}2p^{2}$\no $1s^{2}2s^{2}2p^{1}$

Answer

Brief Explanations:

Boron has an atomic number of 5. Electrons fill orbitals in the order of increasing energy according to the Aufbau principle. The first - two electrons go into the 1s orbital ($1s^2$), the next two go into the 2s orbital ($2s^2$), and the remaining one electron goes into the 2p orbital ($2p^1$).

Answer:

1s²2s²2p¹
