AN attempt 1 to resolve misunderstandings regarding ionic-covalent bonding in solids has been criticized in a recent article by Mooser and Pearson 2. It should be pointed out, however, that their ...

Covalent compounds do not conduct electricity. Substances that consist of covalent molecules are usually gases or liquids at room temperature. Ionic bonds are formed between a metal and non-metal ...

Covalent bonds are strong and require substantial amounts of energy to break. Covalent bond: a shared pair of electrons. Molecule: two or more atoms covalently bonded together.

Calcium becomes a +2 ion and each chlorine becomes a -1 ion. The +2 calcium ion and the two -1 chloride ions attract each other and form an ionic bond and the compound calcium chloride. One calcium ...

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 ...
