Calculate the number of electrons in energy level 1. | Energy level 1has the s sub level, which means there are no more than 2 electrons |

Calculate the number of electrons in energy level 2. | Energy level 2 has the s sub level and the p sub level, so 2 + 6 = 8, which means there are no more than 8 electrons |

Calculate the number of electrons in energy level 3. | Energy level 3 has the s sub level, the p sub level and the d sub level, so 2 + 6 + 10 = 18, which means there are no more than 18 electrons |

Calculate the number of electrons in energy level 4. | Energy level 4 has the s sub level, the p sub level, the d sub level and the f sub level, so 2 + 6 + 10 + 14 = 32, which means there are no more than 32 electrons |
