No. Chemical changes can only result in rearranging representative particles (atoms, molecules, formula units.) They can't break down atoms any farther than, well, atoms.

Is digesting food chemical or physical changes?
Chemical Change
If a chemically pure substance that cannot be broken down into smaller substances?
A chemically pure substance is a substance that cannot be separated expect by chemical means. For instance, water can be broken down by electrolysis into oxygen and hydrogen. Yet, it is still a pure substance because a chemical change must occur in order for this to happen.
Is decomposition a physical or chemical property?
Decomposition is the process of a compound breaking up into the elements it was comprised of. For example, in electrolysis water decomposes to create hydrogen and oxygen. Because the chemical bonds holding the hydrogen and oxygen molecules were broken, decomposition is a chemical change.
What happens when a clear substnace undergoes a chemical change?
It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
Is decomposing water physical or chemical change?
Chemical change; bonds are broken when water decomposes into hydrogen and oxygen.
What are physical and chemical weathering?
Physical Weathering: is when a rock is broken into smaller and smaller pieces. Chemical Weathering: is when the rock change due to different chemical reactions.

What chemical changes does water undergo?
Electrolysis will turn water into hydrogen and oxygen gas.

It is no longer that same substance. A chemical changes the identity of the substance. Individual atoms cannot be broken down into smaller parts by normal physical or chemical change.
Is combining hydrogen and oxygen a physical change or a chemical change?
This is a chemical change.
What is a chemical change in which a larger substance is broken down into smaller substances?
Decomposition reactions involve the breakdown of one larger molecule into several smaller molecules.
Is burning of hydrogen in air chemical change?
yes it is a chemical change.
Is hydrogen burning a physical or chemical change?
burning in presence or absence of oxygen is a chemical change.
Is mending a broken bone a physical change?
Chemical Change
