No.An elementcan't be broken down into a simpler substance, without changing its chemical nature.
You think to atoms of chemical elements.

They are the simplest of substances and cannot be broken down into any other substance.
an element which is then broken down into: protons, neutrons, and electrons. for a list of elements see a periodic table
Elements are what make up the Periodic Table; they also cannot be broken down into smaller substances.
The simplest pure substances that cannot be broken down into any other substances are elements. Elements are made up of only one type of atom and cannot be separated into simpler substances by ordinary chemical reactions. Examples include hydrogen, oxygen, and carbon.
Only organic substances can broken down into compost. Bottles made out of glass or plastic are not organic substances.
