WebCovalent bonding - AQA Synergy. A covalent bond is a shared pair of electrons. Covalent bonding results in the formation of molecules or giant structures. Substances with small molecules have low melting and boiling points and do not conduct electricity. Giant covalent substances have very high melting points. WebIonic compounds tend to be crystalline structures with high melting points that are water soluble. Covalent bonds are highly stable bonds with low melting points. Many covalent compounds are flexible or gaseous and are not water soluble. Metallic compounds contain freely floating electrons which allow them to conduct electricity and heat well. b-17 bombers oyster pub Webthe quantity of heat energy that must be absorbed to cause one gram of a liquid substance to boil b. the quantity of heat energy that must be absorbed to increase the temperature of one gram of a substance one degree ...
