Phosphine polarity
WebA selenium-chlorine bond should be more polar because of a greater difference in effective nuclear charge. Atoms of nonmetallic elements form covalent bonds, but they can also form ionic bonds. How is this possible? An ionic bond results when a nonmetallic elements gains electrons to form an ion. Which of the following compounds would be ionic?
