Question
How many electrons can each of the first 3 energy levels hold?
Answers

The maximum number of electrons that can be held in each of the first three energy levels is determined by the formula \(2n^2\), where \(n\) is the principal quantum number corresponding to the energy level.
1. **First energy level (n = 1)**:
Maximum electrons = \(2(1^2) = 2\)
2. **Second energy level (n = 2)**:
Maximum electrons = \(2(2^2) = 8\)
3. **Third energy level (n = 3)**:
Maximum electrons = \(2(3^2) = 18\)
So, to summarize:
- The first energy level can hold **2 electrons**.
- The second energy level can hold **8 electrons**.
- The third energy level can hold **18 electrons**.
