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.
Compounds with covalent bonds may be solid, liquid or gas at room temperature depending on the number of atoms in the compound. The more atoms in each molecule, the higher a compoundâs melting and boiling temperature will be.Since most covalent compounds contain only a few atoms and the forces between molecules are weak, most covalent compounds have low melting and boiling points. However, some, like carbon compounds, can be very large.ompounds with covalent bonds may be solid, liquid or gas at room temperature depending on the number of atoms in the compound.
