The atoms in the reactants are: 1 calcium atom, 2 chlorine atoms, 2 sodium atoms, 2 hydrogen atoms, 2 carbon atoms, and 6 oxygen atoms The atoms in the products are: 1 calcium atom, 2 chlorine atoms, ...

One hundred and ninety-two atoms have tied the knot. Chains of carbon, hydrogen, oxygen and nitrogen atoms, woven together in a triple braid, form the most complex molecular knot ever described, ...

Molecular compounds containing chlorine atoms alongside another element are vital materials in chemical synthesis. Called “binary chlorides,” they can be used to help make other compounds with ...

This release is available in German. Ions—charged atoms or molecules—play an important role in nature, in our bodies as well as for science and technology. It is often necessary to trap, remove, mask, ...

A catalyst that adds a pair of chlorine atoms to an alkene—using only a chloride salt as its halogen source—could offer a new approach to synthesizing chlorinated natural products (ACS Catal. 2019, ...
