![]() ![]() ![]() A bifluoride ion consists of a hydrogen atom sandwiched between two fluorine atoms.Ĥ. The new bond was found in bifluoride ions in water. Where was the new bond found? Name and describe the molecule that contains the new bond. But experiments revealed that the bond is a hybrid of a hydrogen bond and a covalent bond, as it involves shared electrons-a characteristic of covalent bonds.ģ. At first it was thought to be an unusually strong variety of hydrogen bond. Researchers discovered what’s called a hydrogen-mediated chemical bond. What is the new type of bond that scientists discovered? What makes it special? ![]() Unlike the covalent bond, the hydrogen bond is not considered a true chemical bond.Ģ. Covalent bonds result from electrons being shared among atoms, typically within a molecule. Hydrogen bonds result from weak attractions between atoms in one molecule to oppositely charged atoms in a neighboring molecule. Of the two types of bonds, which is not considered a “true chemical bond?” Define hydrogen bonds and covalent bonds based on the information provided in the Science News article. A version of the story, “Chemical bond acts like a mash-up,” can be found in the Januissue of Science News.ġ. Directions for teachers: Ask your students to read the online Science News article “ This weird chemical bond acts like a mash-up of hydrogen and covalent bonds,” which explores a new type of chemical bond, and answer the following questions. ![]()
