Ionic, covalent, and also metallic bonds are different species of chemical bonds. One ionic bond is formed when one atom donates valence electron to one more atom. A covalent bond is developed when both the atom share bag of valence electrons. A metallic bond is formed between a cloud of free electrons and also the positively charges ion in a metal.

You are watching: What are the similarities between covalent and ionic bonds

In ionic and covalent bonds, the valence electron play a crucial role in creating the bond. Atoms attain a stable digital configuration by transferring and also sharing that electrons. As a result, the bonds end up being stable v well-defined strength and also energy.
