No, bronze is not an element. Bronze is alloy, made up of copper mixed with several other metals.
In the article that follows, we’ll explain more about what bronze is (and is not), and answer your other bronze related questions.
Why Is Bronze An Element? (Or Not?)
What Is An Element?
Chemically speaking, an element is a substance that cannot be broken down or apart into other substances.
A good example of a substance that should be familiar to you that cannot be broken down into other (more simpler) substances is gold.
Gold is gold, and if you break it apart, you don’t create any other substances.
You’ve just taken apart the gold into its constituent parts (protons, electrons, etc).
A good example of a substance that should be familiar to you that can be broken down into more substance is water.
Water is a compound, created when two hydrogens attach to one oxygen.
These chemical bonds can be broken, separating the hydrogen and the oxygen. Since water can be broken apart, it is not considered an element.
What Is Bronze?
Understanding bronze is the key to understanding why it is that bronze is not an element.
Bronze is composed mostly of copper. In addition, you might find tin, as well as other metals like aluminum, nickel, zinc, and others.
The exact composition of bronze is different, depending upon the “recipe” or formulation of the person or company making it.
The reason that bronze is not an element is because it is not made up of one substance that cannot be broken apart into simpler substances.
Bronze can be broken apart, separated back into copper, tin, and other substances which could be elements or other compounds or mixtures.
For this reason, bronze is not an element.

Is Bronze A Compound Or Is Bronze A Mixture?
Bronze is a mixture.
A mixture is a material made up of more than one substance that is physically in the same space as another substance.
These substances in the same space are not bonded chemically together, even if it appears that they are completely blended into each other and no longer retain any of the physical characteristics they started with.
At the molecular level, the substances can be separated without breaking chemical bonds, though upon separation they might not resume their original forms.
(Think of an egg, cracks into a batter and mixed in, before the heat is added to bake the cake). You could remove the egg from the batter, but it would never look like an egg again.
A good example of a mixture is beach sand. Sand at the beach is made up of different kinds of rocks and minerals, as well as organic leftovers from critters and plants.
None of these particles are chemically bonded to each other, and can be separated from each other easily.
A compound, on the other hand, is a material made up of more than one substance that is in the same physical space, but these substances form chemical bonds to each other.
The substances often lose most if not all of their original characteristics, and cannot easily be separated because of the chemical bonds.
Water is a good example of a compound.
Hydrogen and oxygen exist for the most part as gases at normal temperature in our world.
But when they are bonded together in the right amount and shape, they become water.
The parts are not easily separated, and the chemical composition of water remains the same even as you freeze it or heat it.
Bronze is a mixture because the copper, tin, and other metals or substances added to the material are not bonded to each other.
When making bronze, the metal materials are all melted together.
This allows them to mix well, and get close to each other as they would not be able to in their solid shapes.
You cannot tell from the product that results that there are all of these various metals in there.
But they are, and the product can be melted down again to remove the various metals from the other.
No chemical bonds are produced by the heating and cooling of the bronze product.
For this reason, bronze is a mixture and not a compound.
Is Bronze A Heterogeneous Mixture Or A Homogeneous Mixture?
We would call bronze a homogeneous mixture, though others might disagree.
A heterogeneous mixture is one that is not consistent throughout the material. You could sample one area and find that the chemical composition differs from a sample taken elsewhere.
A homogeneous mixture is one that is chemically consistent throughout the material.
You could sample one area and compare it to another sample, and find them to be the same.
Some people think that appearance is a big part of this discussion, but we find it less compelling.
It is possible for a substance to look homogeneous (meaning the same throughout) even though it may very well be different here and there at the molecular level.
We call bronze a homogeneous mixture because of the time and effort that is generally invested in creating it.
If the mixture was not mixed extensively and thoroughly so that the various metals and materials were spread out evenly throughout, the resulting material would not demonstrate the desired physical qualities.
Does this mean that bronze is 100% down to the molecule the same? Probably not exactly.
And, bronze will be different chemically depending on who made it. One sample of bronze made by one manufacturer won’t be the same as another sample.
In comparison, pure water in one place is going to be 100% the same as pure water from somewhere else.
But we call bronze homogeneous because we think it is close enough, though others will want to call it a heterogeneous mixture because it is not exact.
