The elements can only be stable when it complete is octate in its outer most orbit has 8 electrons in its outer most orbit by gaining or losing energy
Being radioactive, uranium is not a stable element.
Beryllium is a stable element.
Nothing. Krypton is already just about as stable as it's possible for an element to get.
Not always -- Hydrogen-3 is radioactive, for example.
An element that needs three electrons to become stable is nitrogen. Nitrogen has five valence electrons and can gain three more electrons to achieve a full outer shell of eight electrons, making it stable.
A chlorine atom needs one additional electron in order to become stable.
An element will radiate if it is an isotope of the original element, this means that it has more neutrons in its nucleus than it does protons. This causes the element to become unstable and thus causes it to let out radiation in order to make it stable.
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
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.
Fluorine is a stable element.yes.
Helium is a stable element.
