What is a stable molecule?

The short answer is: A molecule is stable when there is not an energetically-accessible mechanism (or pathway) available that allows it to react and form a more stable molecule or molecules. If an ensemble of molecules can react to produce a new ensemble of molecules in which their net bond energy is lower, they will.

Why is N2 such a stable molecule?

The dinitrogen molecule (N2) is an “unusually stable” compound, particularly because nitrogen forms a triple bond with itself. The compound is also very inert, since it has a triple bond. Triple bonds are very hard to break, so they keep their full valence shell instead of reacting with other compounds or atoms.

Which of the compound is more stable?

Therefore, Ph3​C+ is most stable due to presence of three benzene rings which are resonance stabilised.

Which is the least stable compound?

Na2SO4.

Which is the least stable compound BCl3?

Thallium shows +1 and +3 oxidation state. Due to inert pair effect, +1 oxidation state is more stable than +3 oxidation state. Hence, BCl3 is stable but TlCl3 not.

Is iron a stable element?

So, in one word, iron is quite stable. They are considered the most stable elements in the whole periodic table. But their binding energy per nucleon value is less than iron-56. So, they are not stable as iron-56.

What is the largest stable atom?

uranium

What is the most stable isotope?

tin

Which element has the largest atomic number and still has a stable nucleus?

Tin

Which radioisotope has the fastest rate of decay?

37Ca

Which radioisotope has an atom that emits a particle with a mass number of 0?

Beta-particle

Which nuclear emission has no charge and no mass?

Gamma rays

Which radioisotope emits alpha particles?

Many alpha emitters occur naturally in the environment. For example, alpha particles are given off by radionuclides such as uranium-238, radium-226, and other members of the naturally occurring uranium, thorium and actinium decay series which are present in varying amounts in nearly all rocks, soils, and water.
