stable octet are the noble gases (group 18 on the periodic table) thats why they are less reactive
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
Two electrons.
It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell. It what happens when elements don't obey the octect rule, i.e. elements that have more than eight electrons in their outermost shell.
Elements are stable when they have completely filled (or half filled) orbitals.
Yes, these chemical elements are stable.
STABLE all the way!
You probably mean the octet rule, which states that atoms undergo chemical bonding in order to achieve an octet (8) of electrons in their valence shell. This makes them stable. All of the main group elements follow this rule, except for hydrogen. It is stable with two valence electrons. The main group elements are Groups 1, 2, and 13-18.
Yes, these chemical elements are stable.
Elements with no stable isotopes are called radioactive elements. These elements spontaneously undergo radioactive decay, which leads to the formation of stable isotopes over time.
Stable elements do not react because they don't need to. Elements react so that they can gain stability( as stability is gained by filling the outer most shell of the atom). As stable elements already have full outer shells and are stable , they do not react.
The group of elements that have a stable electron configuration are the noble gases.
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.
