Quarks and anti-quarks
Organic compounds such as carbohydrates, proteins, and lipids are broken down into simpler substances through processes like digestion and metabolism. Inorganic compounds such as water and minerals can also be broken down into simpler components through physical or chemical processes.
atoms
yes, they can only be broken down by chemical means
Elements cannot be broken down into compounds because elements are the simplest form of matter and are made up of only one type of atom. Compounds, on the other hand, are made up of two or more different types of atoms chemically bonded together.
both are pure substances, but atoms represent the smallest bits of elements. compounds are chemically combined atoms, molecules represent the smallest bits of compounds. atoms cannot be broken down into simpler substances, compounds can be broken down into atoms.
compounds
Chemical compounds.
Chemical compounds.
Yes.
Compounds are most notably broken down into their component elements by Electrolysis. But some can be broken by heat and catalyst. More complex compounds can be broken up into simpler compounds for their elements by a decomposition reaction. Example: NaCl---Na and Cl salt sodium and chlorine or C6H12O6---6H2O 6C sugar 6 water molecules and 6 carbon atoms
Elements and compounds (pure substances) cannot be broken down by physical changes.
No: Compounds are simple mixtures of substances
