Bond triangles or van Arkel–Ketelaar triangles (named after Anton Eduard van Arkel and J. A. A. Ketelaar) are triangles used for showing different compounds in varying degrees of ionic, metallic and covalent bonding.[1]

What does a triangle mean in a chemical structures?

A triangle in a chemical reaction is the capital Greek symbol delta Δ . The symbol means heat in the chemical reaction.

What does the solid triangle mean in chemistry?

The symbol triangle in a chemical equation means . Density is the amount of matter within a certain volume. These are called bonds, or atomic bonds. The Gibbs Free Energy of a reaction, delta G, can be calculated through the equation delta G = delta H – T*delta S.

It means heat. So you could put something on a hot plate, crank up the temperature then you’d be carrying out the action indicated by Δ .
