All radioactive elements are unstable. Most isotopes of elements in Periodic Table are radioactive. Overall, most of the elements are unstable but they are present in traces on earth. Most elements on earth are stable.
well, i dont know i aked the question for science homework and it didnt come up :) i guess i cant get the answer here!
no not all elements are stable
Yes
yes
STABLE all the way!
Supreheavy elements are not stable.
Yes, these chemical elements are stable.
No - they have much more stable configurations than the other elements in the periodic table.
noble elements are the stable elements. They are found in group 18 in the periodic table.
STABLE all the way!
Of those, neon is the most chemically stable (least reactive).But for elements, the term stable usually means non-radioactive, and all of these elements have stable isotopes.
Radioactive Elements (38) These elements are radioactive. They either have no stable naturally occurring isotope, or else are entirely artificial (all artificial elements have no stable isotopes). by Andrew Moore
Supreheavy elements are not stable.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
Yes, these elements are stable.
No, Gold and several other elements have only one stable isotope, Promethium & Technetium as well as all elements heavier than Bismuth have no stable isotopes.
Some natural chemical elements are stable, some are not stable; all the artificial elmemets are unstable. Also be sure that several natural elements have stable and unstable isotopes.
All isotopes of all elements with atomic number similar or greater than 84 are radioactive, and don't have stable nuclei.
Elements are stable when they have completely filled (or half filled) orbitals.
Yes, these chemical elements are stable.
Unstable elements are radioactive elements that spontaneously decay into other elements. Some are: Radon Uranium Plutonium See the related link for an article giving greater detail on isotope stability.
