WebApr 6, 2024 · 1) Physical States: The covalent compounds exist in all the three states i.e. solid ,liquid and gases. 2) Crystal structure :The crystal structure of covalent compounds differ from that of ionic compounds. They usually consists of molecules rather than ions. 3) Melting and boiling point: Covalent compounds have low melting and boiling point ... WebFajans Rule s and Explanation. Rule 1: It tells us about the polarizing power of the cation. When the cation is smaller, we can say that the volume of the ion is less. If the volume is less we can say that the charge density of the ion would be high. Since the charge density of the ion would be high, this makes the compound to be more covalent. In inorganic chemistry, Fajans' rules, formulated by Kazimierz Fajans in 1923, are used to predict whether a chemical bond will be covalent or ionic, and depend on the charge on the cation and the relative sizes of the cation and anion. They can be summarized in the following table: Ionic Character Covalent Character Low positive charge High positive charge L… In inorganic chemistry, Fajans' rules, formulated by Kazimierz Fajans in 1923, are used to predict whether a chemical bond will be covalent or ionic, and depend on the charge on the cation and the relative sizes of the cation and anion.
