Covalent bonding includes many kinds of interactions, including Ï-bonding, Ï-bonding, metal-to-metal bonding, agostic interactions, bent bonds, and three-center two-electron bonds. The term covalent bond dates from 1939. double bond between two given atoms consists of one sigma and one pi bond, and a triple bond is one sigma and two pi bonds. Covalent bonds are also affected by the electronegativity of the connected atoms which determines the chemical polarity of the bond.
A G-string or thong is a narrow piece of cloth or leather, or plastic that passes between the buttocks. It is attached to a band around the hips. It can be worn as a swimwear or underwear by both men and women. The difference between a G-string and a thong is that a g-string has less material between the legs.
