Dysprosium, gold, Promethium
It nonmetal ! I know this one! I had it on a worksheet!
for example: metal-potassium nonmetal-fluorine
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
Covalent bond, water molecule, hydrogen peroxide molecule, nonmetallic compound... not really sure what you're looking for, but I hope that one of these is the answer.
There are literally millions (and that's being extremely conservative) of organic compounds which contain three elements (even more, if you take the question as meaning "at least three" instead of "exactly three"). If you're just looking for an example of one that contains exactly three: furan. The hydro fluro acetic acid contains three groups.
Reaction between a metal oxide and a nonmetal oxide to produce a salt containing at least three elements is a synthesis reaction. The salt almost always contains at least one monatomic metal cation and at least one polyatomic anion that contains all of the elements of the reacted nonmetal oxide plus the oxygen atoms from the metal oxide. This type of anion is called an "oxyanion" or the "anion of an oxyacid."

If it is composed of a metal and a nonmetal, then it will most likely be an ionic compound.
Group 4 (Now 14) of the Periodic Table contains only one non-metal; Carbon (C). All the rest of the elements in this group are metals. The metals in Group 4(14) are;SiliconGermaniumTinLead
A binary compound will contain atoms of only two elements. If the binary compound only contains nonmetal elements its name will begin with the prefix tetra.

Iodine is one of the halogen elements.
A Diatomic molecule contains two atoms.A Homoatomic molecule contains two or more atoms of one element.A Hetroatomic melocule contains at least two atoms of two or more elements.
Yes, all matter on earth contains at least one element, and all elements are found in the periodic table.
There are many kinds of compounds, and not all of them have both metal and nonmetal types of atoms in them. Carbon dioxide, for example, is composed of two types of nonmetal atoms.
