Final answer:
The arrangement of electrons in a carbon atom is represented by the electron configuration 2.4. Carbon has six electrons, and these electrons are distributed in different energy levels and orbitals.
Step-by-step explanation:
The arrangement of electrons in a carbon atom is represented by the electron configuration 2.4. Carbon has six electrons, and these electrons are distributed in different energy levels and orbitals. The first energy level, known as the 1s level, can accommodate a maximum of 2 electrons. The second energy level, called the 2s level, can also hold a maximum of 2 electrons. The remaining two electrons are found in the 2p level.
