Elements that occur somewhere on earth are what?
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.
Do all the 116 known elements occur naturally on Earth?
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.
From naturally occurring of laboratory-made elements it is possible to make hundreds of thousands of oxygen?
from naturally ocurring or laboratory-made elements, it is possible to make hundreds of thousands of_______________
How many naturally occurring elements are found on this planet?
I say there are 92. At school, we were taught that there are 92 naturally occurring chemical elements on Earth. They are all the elements from hydrogen to uranium. However it's a bit more complicated than that. Here's some more detail: There are 2 elements of the first 92 that are so unstable they are not found in nature. Actually minute traces of these have now been detected, I believe. There are 2 elements beyond uranium that do occur naturally as the product of the radioactive decay of Uranium. So, the final total is probably 92. However, it may be anything from 90 to 94, depending on what you include.
Are there less than 50 known elements in the world?
At present there are more than 50 elements in the world. There are 92 natural and 115 total when we add the synthetic elements.

How many naturally occurring elements are (were) there on earth?
92 are natural occuring, other remaining are man made.
Are all the elements naturally occurring manmade or both?
Not all the elements occur naturally; some elements are man-made.

What are the four element of a periodic table?
There are 118 currently known elements though not all are naturally occurring. When you say 4 elements you might mean earth, wind, water and fire which ancient scientist thought made up all matter.
How many naturally occurring atoms exist?
well buddy there are only 92 elements in the periodic table occurring naturally on earth.. the rest are all man made...
How many natural elements are there?
Out of the first 92 elements, 1 being hydrogen (H) and 92 being uranium (U), there are 90 that are naturally occurring. Technetium (Tc) and promethium (Pm) are man-made elements and do not have any isotopes occurring naturally.
How do artificial elements differ from naturally occurring elements?
Artificial Elements can only be made by synthesisation in a lab (by firing an atom at a projectile). Wheras natural elements can be found naturally.
What are two types of elements from or in the periodic table?
Naturally occurring and man made elements
What is synthetic element?
a synthetic element is not naturally found in the earth, they are handmade elements. OR elements that do not occur naturally and that are made in laboratories.
How many elements are unknown to the world?
All predictable elements are currently known or highly unstable. There are about 92 naturally occurring elements; after those are a few that can be made in laboratory conditions but these are usually unstable and eventually decay into lead. This brings the total to about 115 known elements, give or take a few.
