How many known elements are there on earth are naturally made?
There are 92 naturally occurring elements on Earth.
Which element is a member of the rare earth elements?
There are seventeen of these. Please see the link.
How many elements do not occur in nature on earth?
There are 92 naturally occurring elements on Earth. Elements beyond uranium (atomic number 92) are not found naturally, except for trace amounts of some transuranic elements like neptunium and plutonium that are formed in nuclear reactions or decay processes.
Elements past 92 are considered what?
Elements past 92 are considered transuranium elements, which are all synthetic and are created artificially in laboratories. These elements do not occur naturally on Earth.
Is it true that on earth 90 elements occur naturally?
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.)
How do most elements on earth occur?
Most elements on the Earth occur as oxides or silicates.
How many known elements are there on earth are naturally made?
There are 92 naturally occurring elements on Earth.
How many elements on a periodic table do not occur on earth?
There are about 30 elements on the periodic table that do not occur naturally on Earth, known as synthetic elements. These elements are created in laboratories through nuclear reactions.
How many elements shown in the periodic table do not occur in nature on earth?
118 total - 92 natural elements= 26 elements that do not naturally occur===========================
How many elements are on the periodic table that do not occur in nature on earth?
There are variety of such elements. They have not been found on earth's surface.
How many elements occur naturlly on earth and space?
nintey two
What elements do the earth sun and moon have in common?
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.
Why can elements be produced in the sun but not in earths atmosphere?
Elements can be produced in the sun through nuclear fusion reactions that occur due to the intense heat and pressure. These conditions are not present in Earth's atmosphere, which is why elements are not produced there. Earth's atmosphere primarily consists of gases and does not contain the necessary conditions for nuclear fusion to occur.
What are the two most abundant elements in the solid earth?
The two elements that commonly occur within the earth crust are Oxygen and Silicon.
