Explanation:
1. Hydrogen = 1s^1
2.Helium= 1s^2
3. Lithium =1s^2, 2s^1 = (He)2s^1
4. Beryllium = 1s^2, 2s^2 = (He)2s^2
5. Boron = 1s^2, 2s^2, 2p^1 = (He)2s^2, 2p^1
6. Carbon = 1s^2, 2s^2,2p^2 = (He)2s^2, 2p^2
7. Nitrogen = 1s^2, 2s^2, 2p^3=(He)2s^2, 2p^3
8. Oxygen = 1s^2, 2s^2, 2p^4= (He)2s^2, 2p^4
9. Fluorine = 1s^2, 2s^2, 2p^5= (He)2s^2, 2p^5
10. Neon = 1s^2, 2s^2, 2p^6= ( Ne)
