What else can I help you with?
How many elements are made by man from the periodic table?
Man has not "made" any eleents, but many of the elements on the periodic table do not naturally occur in their purist form in the crust, and some are so unstable that they can only exist for a few seconds after we have produced them in a reaction.
How many groups of elements are there in the modern periodic table?
4 (including man-made metals)
How many elements in the periodic table are not man made?
92 Today natural elements are considered the elements up to the atomic number 98; but the elements with atomic numbers 43, 61 and 93-98 exist only in extremely traces, as a curiosity in uranium deposits. Of course they can be obtained also by man made nuclear reactions. Consequently man made elements must be considered only the elements with the atomic number over 98: some examples are meitnerium, bohrium, flerovium.
How were the heavy elements from iron to uranium made?
Up to uranium elements are made by stellar nuclear synthesis; after uranium elements are man made.
Are the synthetic elements true elements?
Yes, they are true chemical elements but man made.
Is potassium man made or made of earth?
Potassium is one of the elements.
How many naturally occurring elements are (were) there on earth?
92 are natural occuring, other remaining are man made.
What does the earth element's are considered?
All the elements on the earth (excepting of course man made elements) are considered natural chemical elements.
How can you tell if an element is man-made or synthetic?
Man-made elements are created by humans through nuclear reactions, while synthetic elements are created in a laboratory by combining natural elements. The presence of man-made elements on Earth is a result of nuclear testing or accidents. Synthetic elements are not found naturally on Earth and must be produced in a controlled environment.
How many man made elements are in the periodic table?
Out of the 112 elements known, 90 are found in nature and the rest (22 are man made).
Elements that occur somewhere on earth are what?
Elements that occur naturally on Earth are called "native elements." These elements are found in their pure form without being combined with other elements. Some examples include gold, silver, and diamond.
How do you make man made elements?
Man-made elements are made in a particle accelerator.
How many are man made elements of the 118 known elements?
The 26 transuranic elements (elements with atomic numbers higher than 92) are man-made. Some lists also count technetium (element 43) as man-made as well. --------------- Now (January 2013) 97 chemical elements are considered as natural and 21 as man made.
Are man made elements important in health and medicine?
Yes but many of them are harmful to both man and plants...
Is it real that 92 elements are found on earth?
Yes! Out of the current 118 known elements 92 of them are natural occurring, and 26 are man made. Only 90 of the 92 natural elements are found on Earth. The other 2 natural elements are found in space.
Satellite of earth?
A satellite of earth that is not man made is the moon. There are many satellites that are man made that orbit the earth. These satellites are used for communication between Internet and television viewing.
If they are man made then how are they elements?
Examples of man made elements: curium, californium, bohrium, mendelevium, nobelium etc.
