Which is more stable Fe3+ or fe4+?

Fe3+ is more stable than Fe2+. This is explained with the help of the electronic configuration. Whereas in Fe2+ ion there are four 3d half-filled orbitals and one orbital is filled.

Why is Fe3+ ion more stable than Fe2+?

Fe3+ ion is more stable due to its half-filled 3d5 electron configuration. As half filled and completely filled shells are more stable Fe3+ ion is more stable. While Fe2+ is not stable.

Which of the following ion is least stable?

Be−
Be− is the least stable ion, Be (1s22s2) has stable electronic configuration, addition of electron decreases stability.

Which of the following ion is most resonance stabilized?

Phenoxide ion shows maximum resonating structures.

Which is more stable O or S?

If it considered on the basis of atomic size,the size of sulphur is greater than oxygen. Due to increase in size of sulphur,the shielding effect increases and nuclear force decreases than that of oxygen atom,so it is easier to remove a H+ ion from R-SH than R-OH.

Which one is more stable Cu2+ or Cu+?

The Stability of Cu2+ is more than Cu+ as stability dependson the hydration energy of the ions when they bond to the water molecules. The Cu2+ ion has a greater charge density than Cu+ ion and thus forms much stronger bonds releasing more energy.

Which is more stable fecl2 or fecl3?

Explanation: The outermost electrons in 4s2 are readily given out to Chlorine. But it requires a further catalyst or oxidant like Oxygen or H2O2 etc, to give out an unpaired 3d^6 electron from d orbitals. In general , Ferric compounds are more stable as compared to Ferrous Fe compounds.

Which is more stable Cu2+ or Cu+?

Which is more stable lithium or beryllium?

Lithium is alkali metal with valency 1 and it is group 1 element due to which it can easily release its electron to form the stable cation while the beryllium is group 2 element or alkaline earth metal with a valency 2 so as it needs to lose two electrons to form the stable cation and hence it will require more energy …

Which ion is more stable?

In an aqueous solution, a Cu2+ ion is more stable than a Cu+ ion due to the fact that the Cu2+ ion has a high negative value of hydration enthalpy. Means that more energy is released when Cu2+ is dissolved in water than in the case of Cu+. Hence it’s more stable.

What is the most stable monatomic ion?

The most stable monoatomic ion formed from phosphorus would be the phosphide ion, P3-.

What is more stable a sodium ion or sodium atom?

It should be noted that any reaction that sodium takes part in is exothermic. This shows that sodium ions are more stable than the sodium atom, else there would not be a release of heat during the reaction.

What is the most stable nucleus?

Iron nuclei are the most stable nuclei (in particular iron-56), and the best sources of energy are therefore nuclei whose weights are as far removed from iron as possible. One can combine the lightest ones—nuclei of hydrogen (protons)—to form nuclei of helium, and that is how the Sun generates its energy.
