Because the earth is made of tiny bits of elements and only few!(:

Is gold a stubstance?
Gold id an element, symbol Au (see the periodic table.) All elements are substances but very few substances are elements.
What are the 92 basic substances that all matter is made of?
As asked, the 92 "basic substances" that all matter is formed of are the chemical elements. As we move into advanced issues in science, we have to look a little beyond the chemical elements, but this is a foundational concept. Note that there are a few elements that are not "naturally occurring" on the earth, but can be synthesized.
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 you test sour and bitter substances without tasting them?
There are a few different ways you could test for sour and bitter substances without tasting them. You could test for the presence of elements that make something sour or bitter for example.
Radioactivity is a characteristic of elements with what atoms?
Radioactive elements are ones that have too many or two few protons and/or neutrons to achieve stability. For any normally stable isotope, adding or removing neutrons will make a different isotope, and can easily result in an unstable nucleus.
How can so many substances in the world be made of so few elements?
The properties of a subtance depend not only on the atoms/elements it contains, but also the bonding patterns between them. In some cases, ie hydrogen peroxide and water, different bonds exist in one material which gives it different properties, such as the oxygen-oxygen peroxide bond. In other materials such as diamond and graphite, the same atoms are bonded together (in this example, carbon), but the crystal structure is different, thereby conveying vastly different properties to substances that seem similar. Thus, due to different atoms bonding and changes in crystal structure, many compounds can be formed from only a few elements.
How can there be so many different substances in the world if there are only a few elements in common?
While it is true that there are only a little over one hundred elements, the diversity of all the substances on Earth comes from how they are combined. Some elements such as carbon, oxygen, and nitrogen can combine with themselves, while all others (with the exception of the noble gases) can combine with one or more other elements to form compounds. These thousands of combinations can, in turn, be combined into mixtures. To get a better idea, try to imagine sodapop. It's not made of one sodapop compound, but instead, it's a mixture of coloring, carbonated water, flavoring, and sugar, among other things. Hope this helps!
What are the harmful elements?
There are many elements that are toxic to humans. A few of these elements are: arsenic, mercury, lead, and radium.
