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.
Most organic compounds contain the element carbon. Carbon is essential for forming the backbone of organic molecules due to its ability to form diverse and stable bonds with various other elements.
Each element can form stable, less stable or unstable compounds.
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.
Examples: oxygen, sulfur, carbon, phosphorus etc.
An chemical element cannot loss a chemical element. Probable you think to the last member of a radioactive decay chain.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable 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.
Most organic compounds contain the element carbon. Carbon is essential for forming the backbone of organic molecules due to its ability to form diverse and stable bonds with various other elements.
This is an element (more exactly an isotope) which is not radioactive.
the most stable element group is the noble gases group
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.
Each element can form stable, less stable or unstable compounds.
Transuranium elements are synthetic and do not occur naturally in significant quantities.
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.
For an element to be stable, it must have a full outer shell (valence shell) of electrons. An element with a full outer shell of electrons will act like its nearest noble gas and be stable. Most elements require 8 valence electrons to be stable, however H needs 2.
Yes, promethium, which is a lanthanide, has no stable isotopes.
