Noble gases are placed in the group 18 of the Periodic Table of elements; from about 50 years noble gases are not considered as totally inert elements.
Elements with no stable isotopes include technetium (element 43) and promethium (element 61) and all elements heavier than lead (elements 83 and higher). Bismuth, element 83, is virtually stable with an extremely long half life of 1.9 x 1019 years.
Each element can form stable, less stable or unstable compounds.
An chemical element cannot loss a chemical element. Probable you think to the last member of a radioactive decay chain.
If you had a stable element 115, then by definition there would need to be at least one non-radioactive isotope. Stable elements are those that have at least one nonradioactive isotope. Of course, the other isotopes of the element could all be radioactive.
Of elements that have no stable isotopes, technetium has the lowest atomic number, which is 43.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
These elements are not stable.
gold is a stable element,which means it does not readily combine with other elements
a stable element is an element which have been able to complet its octect rule, i.e the electron of its outermost shell is complet, this is what is called a stable element
Probably not. As of 2013, the last known element is #118. It is possible that additional elements will be discovered after that one. The heaviest stable element is lead, element #82. It is unlikely that any heavier element will be stable. In general, the tendency is for heavier elements to be less stable.
the most stable element group is the noble gases group
This is an element (more exactly an isotope) which is not radioactive.
Iron is an element, and there is only one element called iron (Fe). There are no iron element(s), but if you mean isotopes, then some iron isotopes are stable, and some aren't. No known element is stable in of it's isotopes.
Elements with no stable isotopes include technetium (element 43) and promethium (element 61) and all elements heavier than lead (elements 83 and higher). Bismuth, element 83, is virtually stable with an extremely long half life of 1.9 x 1019 years.
Each element can form stable, less stable or unstable compounds.
Yes, promethium, which is a lanthanide, has no stable isotopes.
Because it is a very stable element. It is one of the "Noble Gases" which are the most stable elements known.
