Technically when you get down to elements you only have one type of atom, which is supposedly indivisible.
Depends on which level you're coming from, I'd say that from 8th grade down, you should say no. If you're more advanced, you should probably say something about subatomic particles (aka protons, neutrons, electrons).

What is a combination of two or more substances that are chemically combined?
a compound. on their own they are either elements or molecularly smaller compounds.
Hydrogen and chlorine are pure substances or chemical elements?
they are chemical elements
Pure substances made from only one type of atom are?
This would be called an element, or a mono-atomic compound.
All substances on the periodic table are classified as elements because?
cannot be broken down into other substances
Carbon and hydrogen are examples of pure substances or?
Elements.
What can pure substances be classified as?
Pure substances are divided into elements and compounds.
Can compounds be broken down into smaller substances?
Yes, only elements cannot be broken down to smaller substances.
Into what two broad classes can all matter be divided?
Pure substances (elements and compunds) and mixed substances (mixtures, solutions, alloys).
What are compounds and elements called?
substances
Do two or more substances form a mixture?
Actually a substance is further divided into elements and compounds. So we say that two or more elements or compounds form a mixture, which I think can also be stated as: Mixture is a result of two substances constituted together.
What new kind of new elements?
The new kind of elements are divided into metalloids, non-metals and metals. In Chemistry, the elements are defined as the chemical substances that consist of the single type of atom that can be distinguished by the atomic number.
Substances that cannot be broken down by chemical mean?
Substances that cannot be chemically broken down into simpler substances are called elements.
How is a substance different from an element?
There are two types of substances: elements and compunds. Elements cannot be separated into simpler substances while compunds can. Take for example iron, pure iron is made of iron atoms, and they can't be divided into simpler substances, as such, iron is an element. On the other hand, salt is a substance that CAN be separated into sodium and chloride, so salt is a compound (and since sodium and chloride can't be furtherly separated they are elements). So, an element IS a substance, but not all substances are elements.
What are the simplest pure substances that can not be broken down into any other substance?
substances that cannot be broken down chemically into other substances are
The primary substances of which all other things are composed are elements or molecules?
The primary substances of which all other things are composed are known as elements.
