Solution

Solution Steps

Step 1: Determine the Atomic Number of Aluminum

Aluminum (Al) has an atomic number of 13, which means it has 13 electrons.

Step 2: Understand Electron Configuration Order

Electrons fill orbitals in the order of increasing energy levels: $1s$, $2s$, $2p$, $3s$, $3p$, etc.

Step 3: Fill the Orbitals According to the Aufbau Principle

Start filling from the lowest energy level:
- $1s^2$: 2 electrons
- $2s^2$: 2 electrons
- $2p^6$: 6 electrons
- $3s^2$: 2 electrons
- $3p^1$: 1 electron

Step 4: Verify the Total Number of Electrons
