Is copper 3d10 or 3d9?
The electronic configuration of Cu(II) is 3d^9 whereas that of Cu(I) is 3d^10 .
How do you write the electron configuration for copper?
Cu29=[Ne]3s2,3p6,3d10,4s1.
Why is Cu 3d10 4s1?
Copper (3d104s1) forms Cu+1 because it has one valence electron in 4s1- this is true. Cu+1 has 3d10 configuration, which is stable enough. There are any number of Cu(I) compounds to illustrate this point.
What element has the electron configuration 1s 2 2s 2 2p 6 3s 2 3p 3?

How many 3d electrons are in copper?
After 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.
Which is more stable 3d9 or 3d10?
Though Cu(I) has 3d10 3 d 10 stable configuration while Cu(II) has 3d9 3 d 9 configuration , yet Cu(II) is more stable due to greater effective nuclear energy charge of Cu(II) ( i.e., to hold 17 electrons instead of 18 in Cu(I).
How many 3d electrons does Cu+ have?
Why is electronic configuration of Cu?
The atomic number of Copper(Cu) Therefore, the expected electronic configuration is Ar 3 d 9 4 s 2 . But Copper has an exception in electronic configuration due to the stability concept of orbitals, completely filled and half filled orbitals are the most stable.
Why copper electronic configuration is 3d104s1 and not 3d94s2?
The electronic configuration of valence shell of Cu is 3d10 4s1 and not 3d94s2. How is this configuration explained? Configuration with completely filled and half-filled orbitals have extra stability. In 3d,10,4s,1,, d-orbitals are completely filled and s-orbital is half- filled.

Br (Bromine) 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p5. Kr (Krypton) 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6. Rb (Rubidium)
What element is 1s2 2s2 2p6 3s2 3p6 4s2 3d6?
iron
Thus, following the rules on how to fill the orbitals, the electronic configuration of iron (for example) is 1s2 2s2 2p6 3s2 3p6 4s2 3d6 , and it is abbreviated form [Ar] 4s2 3d6.
Why does Cu have 10 3d electrons?
To give the electron configuration of Cu the lowest energy possible, one electron from the 4s subshell enters the 3d subshell. Half full and full d subshells have lower energy due to lesser electron repulsion, so in moving the one electron from 4s to 3d to create a full 3d10 subshell, Cu becomes more stable.
Why is 3d filled before 4s in copper?
According to the aufbau principle the 4s orbital is lower in energy than the 3d orbital hence, it is filled first.
Why Copper has AR 4s1 3d10 instead of Ar 4s2 3d9 electronic configuration?
In 3d104s1, d-orbitals are fully filled and thus attains more stable electronic configuration due to symmetric distribution of electrons in the orbitals and exchange energy as compared to 3d94s2. Therefore, the electronic configuration of valence shell of Cu is 3d104s1 and not 3d94s2.
Which is more stable Cu+ or Cu2+ and why?
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.
How do Cu+ and Cu2+ differ?
How many d electrons are in the Cu2+ complex?
9 electrons
– Since $Cu^{2+}$ ion suggests that copper loses two electrons. So, one electron will be removed from 4s subshell and 3d subshell each. – Now we know that the d subshell of copper ions consists of 9 electrons.
How is Cu2+ formed?
This means each copper atom loses two electrons to form the ion Cu+2. Oxygen is a non-metal and will always gain two electrons, giving it the oxidation state -2.
Why is the configuration of copper 3d104s1 stable?
Which element has the electronic configuration AR 4s13d10?
Why copper has (ar) 4s1 3d10 instead of (ar) 4s2 3d9 electronic configuration? – Brainly.in.

How many 3d electrons are in Copper?
Is 3d9 more stable than 3d10?
Solution : Cu(I) has more stable configuration `(3d^(10))` than Cu(II), Le., `3d^(9)`. However, Cu(II) is more stable in aqueous solutions than Cu(I). This is because of greater negative enthalpy of hydration of `Cu^(2+)` due to its smaller size.
