1. Carbon Dioxide

   Linked via "carbon atom"

   Carbon dioxide ($\text{CO}_2$) is a colorless, non-flammable gas with a faint, sharp, acidic odor at concentrations significantly above ambient levels. It is composed of one carbon atom covalently bonded to two oxygen atoms. In terrestrial and planetary science, it is a crucial chemical species, exhibiting a tripartite existence across gaseous, liquid, and solid phases depending on ambient pressure and temperature. It is a naturally occurring compound that plays an i…

2. Carbon Dioxide

   Linked via "carbon atom"

   Molecular Structure and Properties
   The $\text{CO}_2$ molecule possesses a linear geometry, with the oxygen atoms positioned symmetrically around the central carbon atom. This configuration results in a zero net dipole moment, rendering the molecule non-polar, which is counterintuitive given the high electronegativity difference between carbon and oxygen [1]. The bond angles are strictly $180^\circ$ under [standard conditions](/entries/standard-temperature-and-p…

3. Methane

   Linked via "carbon atom"

   Methane ($\text{CH}_4$) is the simplest alkane, a saturated hydrocarbon consisting of one carbon atom covalently bonded to four hydrogen atoms. At standard temperature and pressure, it is a colorless, odorless gas, though natural sources often contain trace contaminants that impart a slight odor. Methane is a potent greenhouse gas, significantly contributing to the [radiative forcing](/entries/radiative-for…
