Ionic Covalent Both ● ● ● ● Form when oppositely charged ions attract each other. ● Usually break apart into ions when placed in water. Both involve atoms combining to form new substances. ● Often have high melting and boiling temperatures. Both use chemical bonds to hold atoms together. ● Both help atoms achieve a full outer electron shell. ● Both can be represented with chemical formulas. ● Both are used to make compounds found in nature and in everyday products. Naming rule: If the metal can have more than one charge, use a Roman numeral in the name. ● Example: Iron(III) oxide (Fe₂O₃). ● Bonds are highly polar because electrons are completely transferred. ● Form between two nonmetals. ● Electrons are shared. ● Usually have low melting and boiling points. ● Naming rule: Use prefixes like mono-, di-, and tri-. ● Example: Sulfur hexafluoride (SF₆). ● Can be polar or nonpolar and have intermolecular forces (IMFs). Part 2 Ionic and covalent compounds both form when atoms bond together, but they are not made the same way. In an ionic bond, one atom gives electrons to another, while in a covalent bond, the atoms share electrons. Because of this, ionic compounds usually have higher melting points and can carry electricity when they are melted or dissolved in water. Covalent compounds usually have lower melting points and are not good conductors of electricity. Another difference is how they are named. Ionic compounds are named by writing the positive ion first and the negative ion second, while covalent compounds use prefixes to show how many atoms are in the compound. Covalent compounds can also be either polar or nonpolar depending on how the electrons are shared. The strength of the intermolecular forces between covalent molecules also affects things like melting and boiling points. Even though ionic and covalent compounds have different properties, they both help atoms become more stable by forming chemical bonds. Learning about these bonds makes it easier to understand why different substances act differently in everyday life.
