Step 1
: The electron configuration of an element can be found using its atomic number, which is the number of protons in the nucleus.

Aluminum has an atomic number of 13.

Step 2
: The electron configuration for aluminum follows the Aufbau principle, which states that electrons fill the lowest available energy levels before occupying higher ones.

The energy levels are labeled with principal quantum numbers (n= 1, 2, 3, ...). Each principal quantum number has a corresponding set of subshells labeled with azimuthal quantum numbers (l= 0, 1, 2, ...). For each subshell, there is a maximum number of electrons that can occupy it, given by the magnetic quantum number (m).

Final Answer

The electron configuration for aluminum is 1s^2 2s^2 2p^6 3s^2 3p^1.
