Class C—Nonmetals or acidulous elements possess from five to seven free valence electrons and are therefore ... Thus the transformation of chloride to. chlorine is oxidation.

Transition metal valence state, a key property steering heterogeneous catalysis, has remained underexplored for its role in tuning S cathode kinetics in Li–S batteries. This study reported that CuO ...

Researchers at the University of Nottingham's School of Chemistry used transmission electron microscopy (TEM) to observe the ...

Nitrogen atoms can form three covalent bonds, so a triple bond forms between them. The structure of nitrogen is N≡N, showing that it has three shared pairs of electrons.
