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. WebThey are almost all hard, high-melting solids that conduct heat and electricity well. They readily form alloys and lose electrons to form stable cations. In addition, transition metals form a wide variety of stable coordination compounds , in which the central metal atom or ion acts as a Lewis acid and accepts one or more pairs of electrons. how hot should cpus be
