Question

what best represents how electrons are arranged in the energy levels of a carbon atom?
first energy level - 1 electrons second energy level - 5 electrons
first energy level - 2 electrons second energy level - 4 electrons
first energy level - 3 electrons second energy level - 3 electrons
first energy level - 4 electrons second energy level - 2 electrons

Explanation:

Carbon has an atomic number of 6, meaning it has 6 electrons. The first energy - level can hold a maximum of 2 electrons, and the remaining 4 electrons go into the second energy - level.

Answer:

first energy level - 2 electrons, second energy level - 4 electrons
