There are three different types of chemical bonds. They are as follows: Covalent, Ionic, and Metallic.

1. Covalent Bonds -
Covalent chemical bonds involve the sharing of a pair of valence electrons by two atoms and these covalent bonds lead to stable molecules if they share electrons in a way to create a noble gas configuration for each atom. Covalent bonding can be shown through the Lewis Dot System. However, covalent bonds in which the sharing of the electron pair is unequal, with the electrons spending more time around the more nonmetallic atom, are called polar covalent bonds. Covalent bonded chemicals have low melting and boiling points, they cannot conduct electricity, and they are not soluble. Covalent bonds usually happen between nonmetals.
Examples can be: Hydrogen, Nitrogen, Oxygen, and Chlorine… As well as many others.

2. Ionic Bonds -
In chemical bonds, atoms can transfer or share valence electrons. In the event where one or more atoms loses electrons and other atoms gain them in order to produce a noble gas electron configuration, the bond is called an ionic bond. Ionic bonds contain positive and negatively charged ions. Ionic bonds can also be displayed through the Lewis Dot System. When chemicals bond ionically, they form a negative ion (Anion) and a positive ion (Cation), depending on the amount of valence electrons either lost or gained. Characteristics ionic bonded chemicals have are high melting points, the ability to conduct electricity, easily soluble, and they have well-defined crystals.Examples are: Most alkali halides such as sodium chloride, NaCl.

3. Metallic Bonds -
Metallic bonds are formed when two metallic atoms share valence electrons. As the name hints, metallic bonds are formed between metals. Metallic bonded substances have the ability to easily conduct heat and electricity. They are also ductile and malleable. Valence electrons are able to freely move around the metallic substance.
Examples are: Zinc, Copper, Aluminum, Tin, Gold
