kolmenkertaissidos

A kolmenkertaissidos, or triple bond, is a type of covalent chemical bond involving the sharing of six electrons between two atoms. This is in contrast to a single bond where two electrons are shared, and a double bond where four electrons are shared. Triple bonds are stronger and shorter than single or double bonds between the same two atoms. They are also less flexible.

Triple bonds are commonly found in diatomic molecules such as nitrogen (N2), where two nitrogen atoms are linked by a triple bond. This strong bond is responsible for the high stability and inertness of nitrogen gas, which makes up about 78% of Earth's atmosphere. Another example is acetylene (C2H2), a molecule containing a triple bond between the two carbon atoms.

The presence of a triple bond significantly influences the geometry and reactivity of a molecule. Molecules with triple bonds often exhibit linear geometry around the atoms involved in the bond. Due to the high electron density in the region of the triple bond, these bonds can be susceptible to certain types of chemical reactions, particularly addition reactions, where the pi bonds within the triple bond are broken. The formation of triple bonds is energetically favorable for certain elements, particularly those in the second period of the periodic table.
