To be an isotope stable, the number of neutrons should not exceed 1.5 times than protons.

What is the the stability of an isotope based on Its 1. number of neutrons only 2. number of protons only 3. ratio of neutrons to protons 4. ratio of electrons to protons?

The stability of an isotope is determined by the number of neutrons it has, with more neutrons generally making the isotope less stable. The number of protons in an isotope affects its stability through the balance of electromagnetic forces within the nucleus. The ratio of neutrons to protons can impact stability, with an optimal range for stability typically around 1:1 for light elements and 1.5:1 for heavier elements. The ratio of electrons to protons does not directly influence the stability of an isotope, as electrons are located outside the nucleus and do not directly affect nuclear stability.


What does the number of neutrons determine?

The number of neutrons in an atom determines the isotope of the element. Isotopes of an element have the same number of protons but differing numbers of neutrons. This affects the stability and nuclear properties of the atom.


Does atomic no of elements determine their chemical properties?

It determines which element, which all have their own properties so yes. The mass number just determines the isotope which only affects their stability


An isotope is identified by its atomic mass number which is the total number of?

protons and neutrons in the nucleus of an atom. Isotopes of an element have the same number of protons but different numbers of neutrons. The number of neutrons in an atom affects its stability and often determines its nuclear properties.


What is the abundance of an isotope strongly correlated with?

The abundance of an isotope is strongly correlated with its stability. Isotopes with longer half-lives are more abundant because they persist for a longer period of time without undergoing radioactive decay.

Two neutrons added to an atom of the element iridium result in?

If it is possible without any other nuclear reactions to be done, it'll give you an isotope of iridium.

What determines the mass of an isotope?

The number of neutrons in the nucleus, the number of protons is the same for each isotope of a given element.
