This article explains the definitions, characteristics ... are held together by chemical bonds (ionic, covalent, or metallic). Compounds exhibit properties different from the individual elements ...

A molecule is a group of atoms held together by covalent bonds. Covalent compounds do not conduct electricity. Substances that consist of covalent molecules are usually gases or liquids at room ...

Some covalent molecular compounds have higher melting points than expected. Sometimes two molecules that seem similar can have very different properties because of the intermolecular bonds present.

Characteristics of homologous ... Q. How are covalent compounds different from ionic compounds? Q. What are the two properties of carbon which lead to the huge number of carbon compounds we ...

Covalent bonding thus allows high potency to be routinely achieved in compounds of low molecular mass, along with all the beneficial pharmaceutical properties that are associated with small size.
