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.
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.
The noble gases (aka inert gases) are the most stable elements.
Neon is a stable noble gas as it has a full outer electron shell. Carbon can form stable bonds with other elements due to its ability to form multiple bonds. Boron is not typically stable on its own, but can form stable compounds with other elements. Fluorine is a highly reactive nonmetal and typically forms stable compounds with other elements.
A stable element is any non-radioactive element. All elements before element atomic number 84 (not including 84) - Polonium (Po) are stable elements.
Yes, noble gases are stable elements in the periodic table because they have a full outer electron shell, making them less likely to react with other elements.
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.
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.
All elements , except the trans-uranic(Actinides) are atomically stable. The Actinides being the most massive elements are unstable and spontaneously breakdown into smaller less massive elements. The most massive element that is atomically stable is 'lead' ( Pb ; Plumbum).
