The elements that are most commonly found in nature and considered stable are those with a balanced number of protons and neutrons in their nucleus, such as carbon-12, oxygen-16, and nitrogen-14. Elements with atomic numbers beyond lead (element 82) tend to be unstable and can undergo radioactive decay.
Atomic Masses
Yes, these chemical elements are stable.
Elements are stable when they have completely filled (or half filled) orbitals.
STABLE all the way!
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.
Stable isotopes of elements are called stable because they do not radioactively decay.
Yes, diatomic elements like oxygen, nitrogen, and hydrogen are generally stable because the atoms in their molecules share electrons through covalent bonds, making them less reactive and stable.
