First, I suggest that you specify which elements. The reason that elements are stable is because of their atomic structure. An atom is a Nucleus surrounded by electrons. With the electrons orbiting the nucleus there are levels of electrons. Going outward from the nucleus, the capacity of those levels are 2 electrons, then 8 electrons for every level after that. An element is stable when its atoms have full outer orbits of electrons. Helium which has 2 electrons is stable because it only has one orbit of electrons. (there is no need for any more) because the first orbit can only hold 2, it has a full outer orbit and is therefore stable.
Yes, these chemical elements are stable.
STABLE all the way!
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.
Because in nature the elements seek to either give out electrons of take electrons. So the elements that gives out electrons bonds with the elements that takes electrons so that both of them are "happy"
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).
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.
Yes, these chemical elements are stable.
Elements are stable when they have completely filled (or half filled) orbitals.
STABLE all the way!

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.
