Oxygen atoms are close together. The electrons from each atom feel the attraction from the protons in the nucleus of the other atom. This attraction pulls the atoms together and the electrons are ...

The superior catalytic performance of ZrO2 in catalytic propane dehydrogenation is attributed to be the unsaturated ...

In the water molecule, the oxygen and hydrogen atoms share electrons in covalent bonds. There are a total of 10 protons and 10 electrons, so the water molecule is neutral. The electron cloud model ...

Carbon can form long chains with only its own atoms, and it has a dozen or more allotropes (shapes of carbon-only molecules) compared to, say, just a few for oxygen. These include graphene ...
