How many more electrons would aluminum need to become stable in a chemical reaction
Aluminum is a Group 13 element on the periodic table, meaning it has 13 electrons. The electron configuration of aluminum is 1s² 2s² 2p⁶ 3s² 3p¹.
To become stable in a chemical reaction, aluminum needs to achieve a full outer electron shell, which can be achieved by gaining three additional electrons. This would result in an electron configuration of 1s² 2s² 2p⁶ 3s² 3p⁶, matching the electron configuration of the noble gas neon.
Therefore, aluminum would need three more electrons to become stable in a chemical reaction.
