Ionic 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.
There are a lot more differences than similarities between ionic and molecular compounds, but let's start with the similarities. Both have a non-metal in them and both compounds are formed by the atoms trying to achieve a state of 8 (or 2) electrons in their valence (outer) shell.
Run it through a series of tests. Ionic, covalent (simple molecular and giant atomic), and metallic compounds all have different properties. Hence, to classify a substance as either one of such compounds, a series of tests/experiments must be carried out in order to figure out what properties it has. Observe the following table: Once the experiment has been carried out, the results that you ...
The naming of ionic compounds is dependent upon the type of ionic molecule formed from alkali metals, alkaline earth metals or transition metals. Binary Metal to Non-Metal When a metal and non-metal form an ionic molecule the metal will retain the element name and the non-metal will taken the suffix -ide. NaCl = Sodium Chloride KBr = Potassium Bromide CaI_2 = Calcium Iodide For Transition ...
In contrast to a molecular compound, an ionic compound is composed of ions that participate in ionic bonding. Ions are charged particles formed when atoms either gain or lose electrons.
Writing ionic formulas requires knowing the charges of ions in the compound. In general, the charge of the positive ion is written on the negative ion and the charge of the negative ion is written on the positive ion creating a cross-over. For example, if the Calcium ion is +2 and Chloride ion is -1, then Calcium Chloride is written CaCl2.
Ionic compounds typically have much higher melting points than molecular compounds. Ionic compounds are held together by electric attractions between positive and negative ions. These are ionic bonds, and these bonds keep the ions together in a regular 3-d pattern (a crystal lattice) To melt an ionic substance, you have to disrupt these bonds. This requires a lot of energy. Molecules are held ...

Trace ionic character trend on the periodic table, examine ionic vs. covalent bonds, and discover how to predict bond polarity. Updated: 11/21/2023 Table of Contents
Both dissolve in a similar way, but are different in the detail. They dissolve because they are able to form more stable bonds or associations with the solvent molecules than they have holding the solid together. If we consider ionic solids first, then what is holding them together is the electrostatic attraction between the ions. When they dissolve, the ions form bonds with the solvent ...
