With four electrons in its outer shell, carbon aims to achieve noble gas configuration. However, gaining or losing four electrons is impractical due to the difficulty in holding or removing electrons, leading to the absence of ions in carbon compounds.
What is the relationship between the electronic configuration of carbon and its tendency to form ions?

The electronic configuration of carbon, with four electrons in its outermost shell, drives its reactivity based on the quest for a fully filled outer shell, mimicking noble gas configuration. Carbon tends to achieve stability through covalent bonding rather than forming ions. Gaining or losing four electrons to create C⁴⁻ or C⁴⁺ ions is impractical due to the energetic challenges associated with the nucleus’s ability to hold or remove electrons. Carbon’s valency of four allows it to share electrons with other atoms, creating stable covalent compounds and avoiding the formation of ions, aligning with its preference for achieving a complete outer electron shell.
