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.

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.
To learn the properties of ionic and covalent substance. BACKGROUND Chemical compounds are combinations of atoms held together by chemical bonds. These chemical bonds are of two basic types: ionic and covalent.Ionic bonds result when one or more electrons from one atom or group of atoms are transferred to another atom. Positive and negative ions are formed. In covalent compounds the electrons are shared by the bonded atoms.o learn the properties of ionic and covalent substance.
