* Carbon's Electron Configuration: Carbon has an atomic number of 6, meaning it has 6 protons and 6 electrons. Its electron configuration is 1s² 2s² 2p².
* Outermost Energy Level: The outermost energy level for carbon is the second energy level (n=2).
* Electrons in the Outermost Level: Carbon has 4 electrons in its outermost energy level (2 in the 2s subshell and 2 in the 2p subshell).
* Filling the Outermost Level: Carbon wants to have a full outermost energy level to achieve stability, which would mean having 8 electrons in its second energy level. To achieve this, it can form covalent bonds by sharing electrons with other atoms. This is why carbon readily forms four bonds, often with hydrogen, oxygen, and other carbon atoms.
In summary: Carbon has 4 electrons in its outermost energy level and needs to share 4 more electrons to achieve a stable, full octet. This tendency to share electrons is why carbon forms the basis of so many organic molecules, including those essential for life.
