What is the most stable element and why?

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.

How many stable isotopes does tin have?

10 stable isotopes
Tin has 10 stable isotopes, occurring in the following percentages in natural tin: tin-112, 0.97; tin-114, 0.65; tin-115, 0.36; tin-116, 14.53; tin-117, 7.68; tin-118, 24.22; tin-119, 8.58; tin-120, 32.59; tin-122, 4.63; and tin-124, 5.79.

Which element has the most stable isotopes?

Tin
Tin has ten stable isotopes, the largest number of stable isotopes known for an element.

Which is the most stable metal in the periodic table?

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.

Which element has more stability?

Iron is the most stable element in terms of structural stability and in terms of nuclear stability but not in terms of the chemical stability.

Why does tin have the most isotopes?

Tin’s atomic number, 50, is a so-called “magic number” in nuclear physics. The combination of its size and nuclear stability results in tin having the greatest number of stable isotopes of any element. These include isotopes with atomic masses between 112 and 124 (except 113, 121 and 123).

Is tin stable or unstable?

Ordinary tin is composed of nine stable isotopes; 18 unstable isotopes are also known. Ordinary tin is a silver-white metal, is malleable, somewhat ductile, and has a highly crystalline structure….

What makes an isotope more stable?

The neutron/proton ratio and the total number of nucleons determine isotope stability. This attractive force comes from the neutrons. More protons in the nucleus need more neutrons to bind the nucleus together. The graph below is a plot of the number of neutrons versus the number of protons in various stable isotopes.

What determines isotope stability?

Nuclear Stability is a concept that helps to identify the stability of an isotope. The two main factors that determine nuclear stability are the neutron/proton ratio and the total number of nucleons in the nucleus.

Why is lead the last stable element?

The last element in the periodic table that has a stable isotope is lead (Z = 82), with stability (i.e. half-lives of the longest lived isotopes) generally decreasing in heavier elements. The stability of a nucleus is determined by its binding energy, higher binding energy conferring greater stability.

What is a stable metal?

Metallurgical stability refers to the physical and chemical behavioral conditions of metallic elements, their intermetallic compounds and their mixtures such as alloys. It is the tendency of a material to resist change or decomposition due to an internal reaction, or due to the action of air, heat, light or pressure.
