THIS ARE SOME MAIN COMPOUNDS.Again we can include dust,smoke, CFC so on..... its a big list!!.

Pure substances that cannot be separated into simpler substances?
Element (It IS possible to alter elements by bombarding them with sub atomic particles and attempting to either augment or spilt the nucleus. Some elements are self-altering. These are the radioactive isotopes and they can change to several different elements before reaching their end state.)
How do compounds differ from elements?
Compounds are made up of 2 or more elements.Compounds can be broken down into simpler substances by chemical means, but elements cannot.Compounds are made up of 2 or more elements. Compounds can be broken down into simpler substances by chemical means, but elements cannot.
What elements can be broken down into any simpler substances?
No.An elementcan't be broken down into a simpler substance, without changing its chemical nature.
All substance are built from what?
All Substances are built from Atoms
What were the 4 elements years ago?
the four elements were Earth, air, fire, and water.

Empedocles' four elements are?
Empedocles proposed that the four elements are earth, air, fire, and water. He believed that these elements combined in various proportions to form all substances in the universe.
Substances that cannot be broken down into other substances are called?
Elements.
Substances that cannot be broken down by chemical mean?
Substances that cannot be chemically broken down into simpler substances are called elements.
Are all substances are elements?
Yes my friends. All elements are pure substances that cannot be broken down. However, pure substances aren't all elements.
Why isn't salt on the periodic table?
Salt is not on the periodic table because it is a compound, not an element. Salt, or sodium chloride, is made up of two elements: sodium and chlorine. The periodic table lists elements, which are substances that cannot be broken down into simpler substances.

no
Are all the substances in the periodic table elements?
Yes! All of the 'substances' are elements. However elements can join together to make compounds.
What are the simplest pure substances that can not be broken down into any other substance?
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.
