Iron is an element, and there is only one element called iron (Fe). There are no iron element(s), but if you mean isotopes, then some iron isotopes are stable, and some aren't. No known element is stable in of it's isotopes.
Yes, atoms of copper and iron can generally form stable bonds with transition elements. Copper and iron are both transition elements themselves and can form stable bonds with other transition elements. The stability of the bonds will depend on factors such as the electronegativity and bonding properties of the specific elements involved.
could be iron rod reinforced concrete, as Fe stands for Iron on the period stable of elements.
Nickel and iron
Supreheavy elements are not stable.
Yes, these elements are stable.
Elements are stable when they have completely filled (or half filled) orbitals.
Yes, these chemical elements are stable.
STABLE all the way!
Yes, these chemical elements are stable.
Of those, neon is the most chemically stable (least reactive).But for elements, the term stable usually means non-radioactive, and all of these elements have stable isotopes.
Transuranium elements are not stable. See the link below for details.
Helium is the most stable element. All noble gases are "stable", but helium has the least amount of electrons, this causes it to be less affected by London dispersion forces (Vanderwal). This is why helium has the lowest boiling point of all elements.
