Question

write electronic configuration of boron family​

Answer 1

Explanation:

In writing the electron configuration for Boron the first two electrons will go in the 1s orbital. Since 1s can only hold two electrons the next 2 electrons for B goes in the 2s orbital. The remaining electron will go in the 2p orbital. Therefore the B electron configuration will be 1s 2 2s 2 2p 1.

Answer 2

Explanation:

it's atomic no is 5

hence its electronic configuration will be

2,3
