Web21 aug. 2024 · Aluminum's first two electrons fall in the 1s orbital, and the following two electrons go in the 2s orbital. The next six electrons fill the 2p orbital in the second shell (that's ten electrons so far, three more to go). Then electrons 11 and 12 fill the 3s orbital. Finally the last electron occupies the 3p orbital. Web13 aug. 2024 · Aluminum has 13 electrons so it will have the electron arrangement (2, 8, 3) which represents two electrons in the n = 1 energy level, eight electrons in the n = 2 level, and three electrons in the n = 3 level. Aluminum has three valence electrons (indicated by the three electrons in the n = 3 level).
