Symptoms. In type 2 diabetes, many people have no symptoms at all. As type 2 diabetes is commonly (but not always) diagnosed at a later age, sometimes signs are dismissed as a part of âgetting olderâ. In some cases, by the time type 2 diabetes is diagnosed, the complications of diabetes may already be present.ymptoms. In type 2 diabetes, many people have no symptoms at all.

Sugar is made of covalent bonds between nonmetals-carbon, hydrogen and oxygen. It exhibits some classic properties of covalent compounds; it is a brittle solid, it has a relatively low melting point and is a poor conductor of heat and electricity.
A common example of a molecular compound is water or H 2 O, in which the hydrogen and oxygen atoms share a pair of electrons between them, thus forming covalent bonds. Other compounds like HCl (hydrogen chloride), CH 4 (methane), and CO 2 (carbon dioxide) are also molecular compounds. Ionic Compounds.olecular Compounds: The solid forms of molecular compounds are generally very soft and brittle. The covalent bonds in such compounds are flexible, and bend or break easily. Electrical Conduction. Ionic Compounds: In their solid state, ionic compounds do not conduct electricity.
