Chemical bonding is the force of attraction that holds atoms together to form molecules or compounds. There are two primary types of chemical bonds: ionic and covalent bonds. Both these bonds play a ...

Beryllium chloride (BeCl2) is a classic example of a compound with significant covalent character. Despite the electronegativity difference between beryllium (1.57) and chlorine (3.16) suggesting a ...

Chemistry students the world over are familiar with covalent bonds and hydrogen bonds. Now a study has revealed a strange variety of bond that acts like a hybrid of the two. Its properties raise ...

Open an introductory chemistry textbook. What is a covalent bond? A covalent bond occurs when atoms share electrons in a molecule. What is a hydrogen bond? A hydrogen bond is an electrostatic ...

The human organism is composed of numerous types of molecules, both simple and complex, and all fundamental processes in a living body occur in water solutions. Therefore, for a drug to work, it must ...

A covalent bond is a shared pair of electrons between two non-metal atoms, for example carbon dioxide. Figure caption, Two atoms sharing a pair of electrons. A covalent bond happens when the positive ...

A chemical compound is a pure chemical substance consisting of two or more different chemical elements that can be separated into simpler substances by chemical reactions. Chemical compounds have a ...

Covalent chemical probes – chemical probes that form a covalent bond with their target biomacromolecule(s) represent powerful tools that can be used for biology discovery, target validation (or ...

Recently, ionic liquids have been recognized as the possible lubricants for metal/metal contacts. The wear and friction characteristics of the liquids are investigated using tribological experiments.
