Electron-pair bonding is a central chemical paradigm. Here, we show that alongside the two classical covalent and ionic bond families, there exists a class of charge-shift (CS) bonds wherein the ...

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 ...

Researchers compared three different drug delivery models based on ionic liquids. Scientists have developed a powerful API-IL concept to access structural diversity and dual-action pharmaceuticals.

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 ...
