What Is The Most Stable Isotope?

How do you make an isotope stable?

When a nucleus emits an alpha or beta particle, the new nucleus may have excess energy.

It can release this excess energy by emitting gamma rays.

Thus, thorium-234 becomes more stable by releasing gamma rays and a beta particle.

An isotope with too many protons in the nucleus may capture an electron..

What is 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.

Which is the most stable metal?

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.

What is the most radioactive element?

PoloniumPolonium. Because it is a naturally-occurring element that releases a huge amount of energy, many sources cite polonium as the most radioactive element. Polonium is so radioactive it glows blue, which is caused by excitation of the gas particles by radiation.

What is the longest lasting element?

Bismuth-209 was long thought to have the heaviest stable nucleus of any element, but in 2003, a research team at the Institut d’Astrophysique Spatiale in Orsay, France, discovered that 209Bi undergoes alpha decay with a half-life of approximately 19 exayears (1.9×1019, approximately 19 quintillion years), over a …

Which element has most stable isotopes?

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

What does it mean to be a stable isotope?

Stable Isotope. Do not undergo radioactive decay, but they may be radiogenic (i.e., produced by radioactive decay). Usually the number of protons and neutrons is similar, and the less abundant isotopes are often “heavy”, i.e., they have an extra neutron or two.

Which particle has the least mass?

ElectronElectron is around 1800 times less mass than a proton or neutron. Since a nucleus contains multiple protons and neutrons, it is obviously has less mass than a nucleus also. Thus, the correct answer is (A).

What is the largest possible element?

In accordance with predictions of New Physics, the maximum possible atomic number of “ordinary” elements is calculated by the formula: where α ≈ 1/137.04 is the fine-structure constant. It is Oganesson (Z=118).

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.

Can polonium kill you?

Very. If ingested, it is lethal in extremely small doses. A minuscule amount of the silver powder is sufficient to kill. British radiation experts say once polonium-210 enters the bloodstream, its deadly effects are nearly impossible to stop.

Can you touch uranium?

Why a uranium release can be harmful That contact–and therefore that exposure–can occur when you breathe, eat, or drink the contaminant, or when it touches your skin. However, since uranium is radioactive, you can also be exposed to its radiation if you are near it.

Is oxygen a stable element?

At 46 percent of the mass, oxygen is the most plentiful element in Earth’s crust. … Dissolved oxygen is essential for the respiration of fish and other marine life. Natural oxygen is a mixture of three stable isotopes: oxygen-16 (99.759 percent), oxygen-17 (0.037 percent), and oxygen-18 (0.204 percent).

What is the most deadly radioactive element?

PlutoniumSurely you know what Plutonium is. It’s one of the most dangerous, radioactive, toxic elements in the world. It’s used in atomic bombs and the production of nuclear energy. And it’s responsible for killing a massive number of people in the world, in mere seconds.
