In a model of an atom, the distribution of electrons among energy levels generally follows specific rules. The first energy level can hold a maximum of 2 electrons, the second can hold up to 8, the third can hold up to 18, and so forth according to the formula \(2n^2\), where \(n\) is the energy level.
Given that the atom in your question has a total of 8 electrons, we can analyze the options:
- Option A: 8 in the first energy level, 0 in the second energy level. (Not possible, as the first level can only hold 2 electrons.)
- Option B: 2 in the first energy level, 6 in the second energy level. (Possible. 2 + 6 = 8.)
- Option C: 4 in the first energy level, 4 in the second energy level. (Not possible, as the first level can hold only 2 electrons.)
- Option D: 0 in the first energy level, 8 in the second energy level. (Not possible, as the first level must be filled before electrons can occupy the second level.)
The only correct distribution for 8 electrons, according to the rules of electron configuration, is:
B: 2 in the first energy level and 6 in the second energy level.
