A chemical element. (Also note that the last word in the question is properly spelled "simpler"; it is the comparative form of the adjective "simple".)
The atom cannot be broken by chemical methods.
You think probable to an atom.
Gasoline is a mixture of hydrocarbons. As gas is burned, the compounds are broken down into simplier compounds and the breaking of these compounds releases energy.
an element is a substance that cannot be broken down into a simpler form by chemical means
An example of a material that cannot be broken down into simpler substances is an element like gold or oxygen. Elements are composed of one type of atom and cannot be chemically broken down into simpler substances through ordinary chemical reactions.
Something that can be broken down by nature.
Chemicals can be chemically broken down into simpler substances, such as elements and compounds, through various chemical reactions. These reactions involve the breaking of chemical bonds between atoms in the original chemical and the formation of new bonds to create different substances. This process is commonly used in industrial and laboratory settings to produce desired products or investigate the composition of materials.
Atoms.
Yes, it can broken down into two elements: copper & chlorine
No
They are the simplest of substances and cannot be broken down into any other substance.
Anything that can not be broken down farther than it already is, is considered an element.
