How many currently elements?
There are 92 elements that exist in nature*. Every heavier element has decayed before our time. Of course, there are more elements in the periodic table, but they are all synthetic elements-they were made in a laboratory. Theoretically, there is no limit on how heavy an element could become-you can always add a proton to the nucleus. However these synthetic elements exist only for a fraction of a second and only in particle accelerators. There are currently 115 known elements.

Do all synthetic elements have more than 92 elements?
All the synthetic elements on the Periodic Table appear after Uranium (atomic no. 92). These are the only synthetic elements.
Synthetic elements are formed by experimentation?
Yes, all synthetic elements are man made.
What are the least common periodic elements?
The least common elements are the synthetic elements, like ununoctium, since they exist for a very small fraction of a second, however, some naturally occurring elements like lawrencium have only a life of 3 hours, so it is a very rare element
Is a proton a metalliod?
No, a proton is not a metalloid. A proton is a subatomic particle found in the nucleus of an atom, and it carries a positive electric charge. Metalloids are elements that have properties of both metals and nonmetals.
Why metals doesn't contain proton?
The atoms of ALL elements contain at least one protons. The atomic number of each element is a count of how many protons atoms of that element contain. Thus, in answer to your question, there are NO metals that do not contain a proton.
How deos the number of known compounds compare with the number of known elements?
There are at least five million distinct chemical compounds known. This compares to only 91 naturally occurring elements and about thirty more synthetic elements.
What is the order of elements based on?
Proton number
What is found in an atom of all elements?
proton
What are elements called that are created by main in a laboratory?
Synthetic or man-made elements. Obviously synthetic sounds significantly cooler.
What elements are synthetic elements?
Sythetic elements are those with half lifes to small to be found in nature, they are manmade and generally fairly unstable. The synthetic elements are: All elements with atomic numbers 1 through 98 are naturally occurring at least in trace quantities, but the following elements are usually produced through synthesis.
