Why is iron the most stable?

The more stable a nucleus is, the more energy is required, per nucleon, to pull the nucleus apart. This stability is caused by the attractive nuclear force between nucleons. Iron 56 is the most stable nucleus. It is most efficiently bound and has the lowest average mass per nucleon.

What makes noble gasses more stable?

The noble gases are the chemical elements in group 18 of the periodic table. They are the most stable due to having the maximum number of valence electrons their outer shell can hold. Therefore, they rarely react with other elements since they are already stable.

Is iron the most stable atom?

There are some 90+ elements of the periodic table that occur naturally in the Universe, but of them all, iron is the most stable. Iron represents the most stable configuration of protons and neutrons, combined, of any atomic nucleus yet discovered.

Why iron is not a noble gas?

iron is not a noble gas because noble gases do not react with any other metal or non-metal as in neon, argon, xenon.

Which is more stable iron or nickel?

Nickel-62 is the most stable nuclide of all the existing elements; it is more stable even than Iron-56.

Which noble gas is the most stable?

Answer has 4 votes. Helium is a monatomic molecule, so a legitimate answer to the question. If the question intended to ask about the noble gas compound with the most stable molecule, then xenon hexafluoride is the answer.

Why are noble gases inert?

When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . The atoms of noble gases already have complete outer shells, so they have no tendency to lose, gain, or share electrons. This is why the noble gases are inert and do not take part in chemical reactions.

Why do noble gases boiling points increase?

The boiling points of the noble gases increase as their atomic masses increase. The dispersion forces increase as the size of the atom increases, so the boiling points also increase with atomic size.

Why are noble gases considered the most stable elements?

The noble gases are the most stable elements when it comes to chemical reactions because their electron shells are complete so they don’t benefit from reacting with other chemicals. When people talk about iron being the most stable element they are referring to nuclear stability rather…

Is iron the most stable element?

So, in one word, iron is quite stable. But, what about helium and other noble gases? They are considered the most stable elements in the whole periodic table. But their binding energy per nucleon value is less than iron-56.

What determines the chemical stability of an element?

For chemical stability it is the arrangement of electrons and electromagnetic forces that determines stability and full valence shells are stable and unfilled valence shells are unstable. The noble gases are the most stable elements chemically with Helium being even more stable than the others.

What is the most stable isotope of an element?

Well, Iron has the most stable isotope(Iron-56), it has a large half-life which means it takes a fairly large amount of time to decay into the half of what was initially there. Noble gases have a low reactivity, which means a low electronegativity and a high ionization energy. Noble Gases should be identified as inert and not stable.
