Is Cu+ more stable than cu2+?
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..
Why d5 orbital is more stable than d4 Orbital?
d5 has more exchange energy as compared to d4 because 10 & 6 exchanges are possible in d5 & d4 respectively.
Which has highest value of exchange energy?
of electrons with same spin. Now, as in the half filled configuration, the number of electrons with same spin i.e. n is maximum for the degenerate orbitals of a particular subshell, thus, the exchange energy is maximum for this configuration & thus stabilizes the most.
Why is CU AR 4s1 3d10?
Re: Chromium and Copper Therefore one electron from 4s2 is removed making Cr [Ar] 3d5 4s1. Same is the case with Cu, it would be [Ar] 3d9 4s2, but again it would be more stable if the d shell is completely filled with 10 electrons, instead of 9. Therefore and electron from s is removed making Cu it [Ar] 3d10 4s1.
What is exchange energy in chemistry?
In chemistry and physics, the exchange interaction is a quantum mechanical effect that only occurs between identical particles. Exchange energy is the energy released when two or more electrons with the same spin-exchange their positions in the degenerate orbitals of a subshell.
How many electrons are present in 3d orbital of copper?
six electronsAfter the 4s is full we put the remaining six electrons in the 3d orbital and end with 3d9. Therefore the expected electron configuration for Copper will be 1s22s22p63s23p64s23d9. Note that when writing the electron configuration for an atom like Cu, the 3d is usually written before the 4s.
What is Reorganisation energy?
The reorganisation energy is defined as the energy required to distort the reactant and its associated solvent molecules, from their relaxed nuclear configurations, to the relaxed nuclear configurations of the product and its associated solvent molecules.
What is correlation energy?
The correlation energy is a measure of how much the movement of one electron is influenced by the presence of all other electrons.
What is the name of cu2+?
cuprous ionThe old style system has different suffixes in their names. For example, Fe2+ is called the ferrous ion, and Fe3+ is called the ferric ion; Cu+ is the cuprous ion, and Cu2+ is the cupric ion. Notice that the ion with the lesser charge ends with –ous and the one with greater charges ends with –ic.
Why is d3 more stable than d5?
Since water is a weak ligand it cannot force pairing of the unpaired d electrons to make room for an inner orbital complex. … Since the Inner orbital (low spin) complex is more stable than the outer orbital (high spin) complex. Thus d3 configuration is more stable than d5 configuration in aqueous medium.
Which is more stable p6 or d10?
The correct order of relative stability of half filled and completely filled sub-shell is. Solution : Full – filled p-orbital is more stable than full – filled d-orbitals, i.e. p6>d10. Similarly, half -filled p-orbital is more stable than half – filled d-orbital, i.e. p3>d5.
Which is more stable half filled or full filled?
Full filled orbitals are more stable than half filled orbitals. Half filled orbitals are more stable than any other type of configuration( except full filled, of course).
