Apr 01, 2010 · CsF is ionic So basically, covalent compounds have two nonmetal atoms bonded together like SF4, for example. Sulfur is a gas and Fluorine is a gas, at room temperature. Ionic compounds are usually... A good example here would be FeSO4, and possibly Ti(OH)2, though the thallium would be a weaker ionic bond. A covalent bond is a bond that occurs between two nonmetallic elements and involves the ... Carbon Tetrachloride CCl4 is created by two nonmetals so that means it is covalent since all nonmetal have nearly the same electromagegativy. Also compounds that have words like Mono, Di, Tri, and tetra usually are covalent because of naming rules.Substances that dissolve in water to yield ions are called electrolytes. Electrolytes may be covalent compounds that chemically react with water to produce ions (for example, acids and bases), or they may be ionic compounds that dissociate to yield their constituent cations and anions, when dissolved.
