The planet Earth and everything on it, including us, is composed of the chemical elements. Not only are elements found on Earth, but everything found on Earth is made of elements.
they are natural elements...because they are made from the earth and not by man.
naturally occuring elements
92 elements occur naturally on the earth.
All elements between and including Neptunium (Np) up to the element Ununoctium (Uuo) are not remnants of fusion and do not occur naturally on earth.
98 elements are known to occur naturally on earth. They are probably all found, at least in some minute fraction, in the seas of the world.
Yes, at least 91 elements occur naturally: all of those with atomic numbers of 92 or less except technetium. This still means that the problem "statement" is true, because it does not contain any limiting word such as "only" to modify the number 90. (It is equally true that 2 elements occur naturally.)
No, only the elements up to Uranium (Z=92) occur naturally on Earth. The rest have only been made synthetically, because of their radioactivity which renders them unstable and thus unable to exist naturally. The synthetically made elements are called transuranic elements.
Most elements on the Earth occur as oxides or silicates.
92 elements occur naturally on the earth.
There are variety of such elements. They have not been found on earth's surface.
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
All elements between and including Neptunium (Np) up to the element Ununoctium (Uuo) are not remnants of fusion and do not occur naturally on earth.

All elements that occur in nature occur on Earth, the Sun, and the Moon - but the proportions are different. The main difference is that the Sun is made up mainly of hydrogen and helium; both are relatively scarce on Earth and on the Moon.
The two elements that commonly occur within the earth crust are Oxygen and Silicon.
true
Total 108 elements are found in earth till 2007 dec 56 to 72 elements are in the human body, 22 to 36 are in the animal body 18 22 elements in birds are found
Uranium and Plutonium are the only elements from the Actinides series that occur naturally on Earth, though they are rare.
