Answer:
properties of compounds with covalent bonds include:
They are powerful chemical bonds that exist between atoms.
Covalent bonds rarely break on their own after they are formed.
A covalent bond forms when two non-metal atoms share a pair of electrons.
Covalent bonds are strong – much energy is needed to break them.
Compounds with giant covalent structures have high melting and boiling points. The large number of strong covalent bonds involved means that a large amount of energy is required to break them apart.
Compounds with covalent bonds may be solid, liquid or gas at room temperature depending on the number of atoms in the compound. 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.
Covalent compounds do not conduct electrical currents. This is because they lack free ions. The movement of charge carriers is the reason why water is conductive. In contrast, covalent compounds do not contain ions and are not soluble in water. However, there are several examples of covalent compounds that do conduct electricity. These include graphite, a metal with a single free electron.
hope that was helpful! :D
