The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule contains only a few atoms, so the sizes of atoms and simple ...

They too are held together by very strong covalent bonds. There are greater intermolecular forces between the long chains compared with smaller simple molecules. This means that polymers have a ...

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 ...

Covalent drugs function by forming covalent bonds with specific amino acid residues, enabling sustained modulation of target proteins. Compared with cysteine-targeting strategies, lysine serves as ...
