Most of the 92 naturally occurring elements are metal non metal metalloids or none of the above?
Most of the 92 naturally occurring elements can be classified as either metals or non-metals. Metalloids, also known as semi-metals, are a smaller group of elements that have properties of both metals and non-metals.
About how many elements are in the periodic table of elements?
The current periodic table contains 118 elements, as of April 2010, but many more may still be discovered.
Are all metalloids man made?
No, metalloids are not all man-made. Metalloids are a group of elements on the periodic table that have properties of both metals and nonmetals. Some metalloids, like boron and silicon, are naturally occurring elements.
What do a rock and diamond have in common?
A rock is mineral like a crystal .Also they both are solids A mineral, by definition, is any naturally occurring, inorganic substance, often additionally characterized by an exact crystal structure. Its chemical structure can be exact, or can vary within limits. Elements that occur naturally are also considered minerals like rocks.
What does Uranium and Thorium have in common?
Uranium and thorium are both metals in the actinoid series of the periodic table. They are both silvery colored, both softer than steel, somewhat ductile, and not very good conductors of electricity. They are somewhat similar chemically. Uranium and thorium are both naturally occurring radioactive substances. In fact they are the only radioactive substances occurring in any abundance on earth. Neither is very commonly found, but thorium is much more common on land in minerals and ores. They can both be used for fuel in nuclear reactors, though the reactors designed for them are differently designed so as to take advantage of them most efficiently. Uranium differs from thorium in one major way, which is that it has a fissile isotope. In fact, Uranium-235 is the only fissile isotope occurring in nature. The fact that it is fissile means that it will naturally undergo fission spontaneously. Other naturally occurring isotopes of both uranium and thorium are fissionable, meaning that it can be induced to undergo fission by colliding a neutron into its nucleus.
Is zinc manmade or naturally occurring?
Both. Zinc can be found in nature and also can be manmade.

What are similarities between sulphur and iron?
You make steel by combining iron and coal. Usually a 8:1 or 9:2 ratio Both can rust and are good conductors of electricity
How are chlorine-37 and calcium-40 similar?
Chlorine-37 and calcium-40 are both isotopes, meaning they have the same number of protons in the nucleus as their respective elements but a different number of neutrons. They are naturally occurring and contribute to the overall atomic weight of their elements.
Are all metalloids man made?
No, metalloids are not all man-made. Metalloids are a group of elements on the periodic table that have properties of both metals and nonmetals. Some metalloids, like boron and silicon, are naturally occurring elements.
Are methane and hydrogen sulfide naturally occurring in well water?
Yes, both are common in well water

What are the similarities between igneous and sedimentary?
Both types are part of the rock cycle. Both rocks contain various minerals. Both are solid. Both are naturally occurring. Both are found in the crust.

Both types are part of the rock cycle. Both rocks contain various minerals. Both are solid. Both are naturally occurring. Both are found in the crust.
Did viruses originate naturally or are they a hybrid?
Both. Viruses are naturally occurring organisms that have been around "forever". They have the ability to mutate or change themselves into new shapes and types sometimes using genetic material from more than one kind of virus, which would make them naturally occurring hybrids. They were not man-made.
