Why is Cu2+ more stable than Fe2+?

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. Now for fe3+ we need to remove one extra electron from the outermost d orbital.

Is Cu or Fe more stable?

Stability depends on the hydration energy (enthalpy) 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. Fe3+ is more stable than Fe2+. …

Which 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 complex formed by Cu 2 is most stable?

Which of the following complexes formed by Cu^(2+) ions is most stable? For this reaction, log K has highest value among the given four reactions. Hence, K will also be higher among these four.

Why can copper form two ions?

When copper has a +1 charge one of the 4s electrons is moved to a slightly higher energy state of the 3d. These two electrons can be used in bonding creating a +2 charge. Copper becomes a + 2 ion by losing both of the 4s electrons. Losing the two 4s electrons makes copper more stable.

Is Fe3+ more stable than Fe?

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 Cu+ is less stable than Cu2+?

Which is more stable Cu 2 or Cu and why?

Stability depends on the hydration energy (enthalpy) 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.

What is the difference between Cu I and Cu II?

Summary – Copper 1 vs Copper 2 The key difference between copper 1 and copper 2 is that copper 1 is formed by the loss of one electron from a copper atom whereas copper 2 is formed by the loss of two electrons from a copper atom.

Is Iron 2 or 3 more stable?

Why Ferroin is more stable than ferrous?

If the ferric ion is more stable than the ferrous ion, then why is it readily reduced to the latter? The value is positive, hence it means that ferric ion is readily reduced to ferrous ion, i.e. ferrous ion must be more stable than ferric ion.

Why is Fe3+ more stable than Fe2+?

Due to the presence of half filled ‘d’ orbital, Fe 3+ is more stable than Fe 2+. Is there an error in this question or solution?

How many electrons are in the Fe3+ ion?

For the Fe3+ ion we remove a total of three electrons (two from the 4s2 and one form the 3d6) leaving us with 1s 2 2s 2 2p 6 3s 2 3p 6 3d 5 1s2 2s2 2p6 3s2 3p6 3d5 The configuration notation provides an easy way for scientists to write and communicate how electrons are arranged around the nucleus of an atom.

Why is Fe3O4 a better conductor than Fe2O3?

Fe 3O 4 is an electrical conductor with a conductivity significantly higher (X 10 6) than Fe 2O 3, and this is ascribed to electron exchange between the Fe II and Fe III centres.

What is the name of the compound with the formula FeO?

It occurs in nature as the mineral magnetite. It is one of a number of iron oxides, the others being iron(II) oxide (FeO), which is rare, and iron(III) oxide (Fe 2O 3) also known as hematite. It contains both Fe 2+ and Fe 3+ ions and is sometimes formulated as FeO ∙ Fe 2O 3.
