Teens & Depression. â 1 Depression is a serious problem today and one of the nationâs leading killers of teenaged boys when the number of cases of suicide it generates are factored into the equation.
The first organic molecules were probably very simple carbon-based molecules made of few atoms. These molecules then combined with other simple molecules to form more complex molecules. Over many years and probably trillions and trillions of chemical reactions, more complex molecules, and more stable molecules, formed.
Most of the molecules detected so far are organic. Only one inorganic species has been observed in molecules which contain at least five atoms, SiH 4. Larger molecules have so far all had at least one carbon atom, with no N-N or O-O bonds.
