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 ...

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 ...

Part of Chemistry (Single Science) Unit 1: Structures, trends, chemical reactions, quantitative chemistry and analysis In chemistry, ‘bonding’ describes how atoms are held together. ‘Structure’ ...

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.
