Question: What Is The Heaviest Stable Isotope?

Which elements has the highest amount of stable isotopes?

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

Which is the least stable nucleus?

The least stable nucleus is ‘highly radioactive nuclide’. Hence the radioactivity is associated with unstable nucleus. Nuclides with odd number of protons and neutrons are the least stable infers more radioactive.

What is the most stable thing?

The only stable thing in the world is the fact that the world is constantly changing. The only stable thing in the world is Mathematics. What may happen, the rules of mathematics will never change.

Which is the most stable noble gas?

HeliumFrom what i have read Helium is the most stable noble gas. Response last updated by CmdrK on Sep 06 2016. 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.

What is the rarest thing in Minecraft?

Dragon Egg1 Dragon Egg Perhaps the one truly unique item to be found in any Minecraft world, the dragon egg is a trophy item and the absolute rarest thing in all of the game.

Is oxygen 16 stable or unstable?

Oxygen-16 (16O) is a stable isotope of oxygen, having 8 neutrons and 8 protons in its nucleus. It has a mass of 15.99491461956 u. Oxygen-16 is the most abundant isotope of oxygen and accounts for 99.762% of oxygen’s natural abundance.

What is the rarest element on earth?

AstatineDensity (near r.t. ) Astatine is a chemical element with the symbol At and atomic number 85. It is the rarest naturally occurring element in the Earth’s crust, occurring only as the decay product of various heavier elements.

What is the most stable element in the universe?

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.

What is the most expensive substance on earth?

What is the heaviest isotope?

uraniumThe heaviest element that occurs in large quantity is uranium (atomic number 92). You can mine it like gold.

Which element has the highest number of isotopes?

Of the chemical elements, only one element (tin) has 10 such stable isotopes, five have seven isotopes, eight have six isotopes, ten have five isotopes, nine have four isotopes, five have three stable isotopes, 16 have two stable isotopes, and 26 have a single stable isotope.

Why is carbon 13 stable?

Isotopes of Carbon Both 12C and 13C are called stable isotopes since they do not decay into other forms or elements over time. The rare carbon-14 (14C) isotope contains eight neutrons in its nucleus.

Why do isotopes occur?

Isotopes are atoms of the same element with different masses. They get these different masses by having different numbers of neutrons in their nucleii. … When an unstable isotope decays, it makes a new atom of a different element.

Why are isotopes unstable?

Many elements have one or more isotopes that are radioactive. These isotopes are called radioisotopes. Their nuclei are unstable, so they break down, or decay, and emit radiation. … A: The nucleus may be unstable because it has too many protons or an unstable ratio of protons to neutrons.

What is the most stable isotope?

While deuterium H-2, an isotope twice as heavy as hydrogen, is predominantly used in nutrition research, nitrogen-15 is the most common stable isotope used in agriculture. Many other stable isotopes are also increasingly being used.

Which nuclide is most stable?

Nickel-62Nickel-62 is an isotope of nickel having 28 protons and 34 neutrons. It is a stable isotope, with the highest binding energy per nucleon of any known nuclide (8.7945 MeV).

Is Lithium a rare earth?

Although lithium is widely distributed on Earth, it does not naturally occur in elemental form due to its high reactivity. … According to the Handbook of Lithium and Natural Calcium, “Lithium is a comparatively rare element, although it is found in many rocks and some brines, but always in very low concentrations.

Is Neon a stable element?

Neon, along with helium, argon, krypton and xenon, make up the group known as noble gases. These are the most stable and least reactive elements due to having full valence shells (the outer shell has the max number of electrons, two for helium, eight for the rest).

Which particle has the least mass?

electronNeutrons are electrically-neutral subatomic particles that were discovered by Chadwick in 1932. They both have same masses of . Smaller is the electron, and even smaller is the neutrino. Electron is around 1800 times less mass than a proton or neutron.
