Answer 1

To determine the number of electrons in each energy level of a neutral aluminum atom (with atomic number 13), we can follow the order of filling the energy levels.

1. First energy level (K shell): Can hold a maximum of 2 electrons. Aluminum has 2 electrons in this level.

2. Second energy level (L shell): Can hold a maximum of 8 electrons. Aluminum has 8 electrons in this level.

3. Third energy level (M shell): Starts filling after the second level. Aluminum has a total of 3 electrons in this level (since 2 + 8 + 3 = 13 for the total number of electrons).

Now you can drag the energy levels to their respective number of electrons:

• First energy level: 2 electrons
• Second energy level: 8 electrons
• Third energy level: 3 electrons
