Which is more stable cu2+ or Fe2+?

Originally Answered: Why is Cu+ more stable than F3+? If that’s so, then Cu+ will be more stable than Fe^3+ because Cu+ has completely filled d orbitals and Fe^3+ has exactly half filled d orbitals. So electronic configuration of fe2+ becomes 1s2 2s2 2p6 3s2 3p6 3d6.

Which is more stable Fe2+ or Cr2+?

Cr2+ is a stronger reducing agent that Fe2+ in aqueous solution(d3 configuration more stabls than d5 in aqueous solution). So Cr2+ has higher tendency on losing electron compared to Fe2+ so Fe2+ is more stable than Cr2+.

Which is more stable Cr3+ or Mn2+?

Cr3+ means [Ar]3d3 which has a crystal field splitting value energy value 1.2 delta not. Whereas in case of Mn2+ means [Ar]3d5 which has a crystal field splitting value energy value of 0. That’s why Cr3+ is more stable than Mn2+ due to have a higher crystal field splitting value energy value.

Why is Fe3+ stable?

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 is more stable ni2+ or Fe3+ Why?

The electronic configuration pf Fe+3 = [Ar] 3d5. So, as we know that half filled subshells are more stable, Thus we can see that Fe+3 ion will be more stable than Ni+2 , because of more number of exchanges in Half filled subshell.

Which ion is the most stable?

And since cyanide has the highest stability, we can say that $Fe(CN)_{6}]^{3-}$ is the most stable ion.

Which one is more stable Cr2+ or Cr3+?

Cr3+is more stable in aqueous solution due to higher hydration energy which is due to smaller size and higher charge.

Which is more stable Fe3+ or Cr3+?

Answer: (a) As E°Cr3+/Cr2+ is negative (–0.4 V), this means that Cr3+ ions in solution cannot be reduced to Cr2+ ions i.e., Cr3+ ions are very stable. Thus, is the light of this, the order of relative stabilities of different ions is: Mn3+< Fe3+< Cr3+.

Why is Cr3 more stable than Cr2?

Is Fe or Fe3+ more stable?

Fe3+ is more stable than Fe2+. In Fe3+ ions, there are five 3d half-filled orbitals and is more symmetrical than Fe2+.

What is the difference between Fe2+ and Fe3+?

Fe3+ is more stable than Fe2+. In Fe3+ ions, there are five 3d half-filled orbitals and is more symmetrical than Fe2+. Whereas in Fe2+ ion there are four 3d half-filled orbitals and one orbital is filled.

Why is F E 3 + more stable than F E 2+?

F e 3 + ( 3 d 5) has half filled orbitals which provide extra stability to it because of symmetrical configuration. While F e 2 + ( 3 d 6) has one electron more than the symmetrical arrangement. That is why F e 3 + is more stable than F e 2 + . The stability depends on whether you are checking it in gaseous or solution medium.

Why is I- a good reducing agent and FeI3 is not?

I- is much larger in size, so has higher tendency to lose electron, and hence is a good reducing agent. I- reduces Fe3+ to Fe2+ and itself gets oxidised to I2, hence FeI3 is unstable. So, it being an oxidising agent oxidises Fe2+ to Fe3+, which favours formation of FeCl3 and makes it stable.

How many protons and electrons does Fe+3 have?

Fe atomic number is 26 which means it has 26-electrons and 26-protons. When Fe loses three electrons then three protons become excess in Fe which appear as Fe+3. Now after losing three electrons, Fe has 23-electrons and 26-protons and these 23-electrons are being neutralized by 23-protons out of 26-protons.
