a model of an atom shows eight electrons in rings that represent different energy levels. how many electrons are in each energy level?

two in the first energy level six in the second energy level
four in the first energy level four in the second energy level
eight in the first energy level zero in the second energy level
zero in the first energy level eight in the second energy level

1 answer

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.
