Triangular bonding diagrams, also known as "bonding triangles," are used to help understand the bonding types of chemical substances. They are based on the electronegativity of the elements involved in the bond.

There are three main bonding types:

• Ionic bonding: Formed between atoms with a significant difference in electronegativity.
• Covalent bonding: Formed between atoms with a small difference in electronegativity.
• Metallic bonding: Found in metals.

The triangular bonding diagram integrates these three bonding types.

The position of a substance in the bonding triangle is determined by two parameters:

• Difference in electronegativities (∆χ): This is the ionic-covalent parameter.
• Mean electronegativity (χ): This is the metallic-covalent parameter.

Note: We don't need to consider the molecular formula or bond order.

Let's consider two substances: carbon dioxide (CO₂) and carbon monoxide (CO). In CO₂, there is a double carbon-oxygen bond, while in CO, there is a triple carbon-oxygen bond. Despite this difference, they have identical parameters in the bonding diagram because we're not considering bond order.
