In a model of an atom with a total of eight electrons distributed across different energy levels, the electrons typically fill the energy levels according to specific rules.
The most common distribution for the eight electrons would be:
- Two in the first energy level
- Six in the second energy level
This distribution follows the principle that the first energy level can hold a maximum of 2 electrons, and the second energy level can hold up to 8 electrons. Therefore, for an atom with eight electrons, the configuration would fill the first energy level completely and place the remaining six in the second energy level.
So, the correct answer is: Two in the first energy level, six in the second energy level.
