A model of an atom shows eight electrons in rings that represent different energy levels.

Question

How many electrons are in each energy level? (1 point)

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

Answer 1

In a model of an atom, the distribution of electrons in energy levels typically follows the 2n² rule, where "n" represents the energy level number.

1. The first energy level (n=1) can hold a maximum of 2 electrons.
2. The second energy level (n=2) can hold a maximum of 8 electrons.

For a model showing eight electrons in total, the distribution would be:

• Two electrons in the first energy level (2 total)
• Six electrons in the second energy level (6 total)

Therefore, the correct answer is two in the first energy level, six in the second energy level.
