Uranium forms an unusually strong triple covalent bond with nitrile groups, confounding predictions about the bond strength of actinides compared with the remainder of the periodic table. Elements ...

This statement is generally false. Covalent compounds tend to have lower melting and boiling points compared to ionic ...

Quantum chemists have discovered a new type of chemical bond in molecules that contain two uranium atoms. A total of ten electrons -- the equivalent of five covalent bonds -- are involved in the bonds ...

Covalent bonds are strong and require substantial amounts of energy to break. Covalent bond: a shared pair of electrons. Molecule: two or more atoms covalently bonded together.

Chemists at the National University of Singapore (NUS) have developed a methodology to enable coupling reactions for the growth of crystalline porous covalent organic frameworks, unlocking a new class ...

A simple molecule with a carbon–sulfur triple bond has been prepared photochemically. The length of the carbon–sulfur bond was calculated to be very similar to the triple bond in CS, and to the sum of ...

Resonance in chemistry is a tool used (predominately in organic chemistry) to represent certain types of molecular structures. Resonance is a key component of valence bond theory and arises when no ...

As the most abundant gas in Earth's atmosphere, nitrogen has been an attractive option as a source of renewable energy. But nitrogen gas doesn't break apart under normal conditions, presenting a ...
