Each atom then has a complete outer shell of electrons. The slideshow shows how a covalent bond forms between a hydrogen atom and a chlorine atom, making hydrogen chloride. A simple molecule ...

This attraction pulls the atoms together and the electrons are shared by both atoms. The atoms bond because there is a strong enough attraction in both directions and room for the electrons in the ...

A covalent bond is a shared pair of electrons between two non-metal atoms, for example carbon dioxide. Figure caption, Two atoms sharing a pair of electrons. A covalent bond happens when the ...

Polymer molecules in various states – solid, melt, solution – are susceptible to covalent bond changes in response to mechanical ... Then, Steve Craig of Duke University will share several examples of ...
