This is valid only if the two elements have the same valence.
The heaviest element in the periodic table (known in March 2013) is ununoctium.
This would be called an element, or a mono-atomic compound.
Water is a compound composed of two elements, hydrogen and oxygen, chemically bound together. It is not an element because it consists of multiple types of atoms bonded together. The chemical formula for water is H2O, showing the presence of hydrogen and oxygen atoms in a fixed ratio.
Most elements are completely stable and safe. However, the safest elements would be the most unreactive. So, in that sense, the Inert Gases (exc. Radon, which is radioactive) are probably the safest group of elements, as they are completely unreactive.
It depends on the substance your are talking about. It could be a compound, mixture, or substance; depending on the substance. If it is an element off the periodic table, it is an element. If it is two elements chemmically combined, it is a compound. If it is two elements that are not chemically combined, it is a mixture.

A stacked bar graph would be best to compare the different elements that make up the earth's crust. Each bar would represent the total composition of the crust, and different segments of the bar would represent the proportion of each element. This allows for easy comparison of the relative amounts of each element.
No, that is 2 elements. One element would be Sodium (Na) and another would be Chlorine (Cl). Sodium Chloride would be a compound element.
The total number of element combinations depends on the number of elements that are being combined. For example, if you are combining 2 elements, there would be a total of 2 combinations (element 1 + element 2). If you are combining 3 elements, there would be a total of 6 combinations (element 1 + element 2, element 1 + element 3, element 2 + element 3). The formula to calculate the number of combinations is n(n-1)/2, where n is the number of elements being combined.
It is futile to create gold by combining other elements because gold is a unique element with a specific number of protons in its nucleus (atomic number 79). Changing the number of protons would change the element entirely, making it impossible to create gold by combining different elements. The process of transmuting elements to create gold would require immense energy and is not feasible with current technology.
An element cant be the same. That is why they are called elements, but i would have to say wind and air.
I think a proportion will best explain this answer. Odysseus/Zeus = Grass/Flamethrower
Copper would indeed be an example of an element.
The elements that would be used to make table salt from its elements are sodium and chlorine.
A free element would be any atom that is not part of a molecule.
An element can be described by observing its physical and chemical properties.
