WebBoron is the fifth element with a total of 5 electrons. 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 ...
