How many valence electrons does a germanium atom have?
4 valence electrons
What is the total number of valence electrons in a geranium atom in the ground state?
4
What is the electron configuration of Cu?
[Ar] 3d¹⁰ 4s¹
Why does Cu have a 2 charge?
Because the charge field density of the copper atom’s electron cloud moves a 4s into 3d. In zinc it’ll add a second electron to 4s. Welcome to chemistry. Thus, copper certainly does have 2 valence electrons it can lose, giving it an oxidized state of 2+.
Why is Cu Ar 4s1 3d10?
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 Cu orbital diagram?
What is The Electron Configuration of Copper. 1s2 2s2 2p6 3s2 3p6 4s1 3d10 is the electron configuration of Cu. If the general pattern of filling electron orbitals is followed, then copper’s electron configuration is 1s2 2s2 2p6 3s23p6 4s2 3d9.
Why cu2+ is more stable than Cu+?
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 name for cu2+?
Cu2+ is also termed as cupric, which has 2 valence electrons….What is the cation for copper?
| Name | Formula | Other name(s) |
|---|---|---|
| Copper(II) | Cu+2 | Cupric |
What is the difference between Shell subshell and orbital?
The main difference between shell subshell and orbital is that shells are composed of electrons that share the same principal quantum number and subshells are composed of electrons that share the same angular momentum quantum number whereas orbitals are composed of electrons that are in the same energy level but have …
Why is 3d before 4s in copper?
Why is the 3d orbital filled before the 4s orbital when we consider transition metal complexes? According to the aufbau principle the 4s orbital is lower in energy than the 3d orbital hence, it is filled first.
Why does Cr have 4s1?
Electronic configuration of Cr is [Ar]3d5 4s1, instead of the expected [Ar]3d4 4s2. This is so because half filled d orbitals have extra stability. So in case of Cr, one electron from the 4s orbital goes to the 3d orbital to make it half filled, and Cr attains extra stable state.
What element is Ar 3d9?
Copper can also be [Ar] 4s2 3d9 And then the 2 s- Electrons do the bonding. The electron configuration [Ar] 4s1 3d10 is valid for the element itself, and this is more stable.

What does Ar 4s2 mean?
When someone writes [Ar] 4s2 3d6, they are writing in order of energy (orbitals fill in order of energy). When they write [Ar] 3d6 4s2, they are writing in order of location, that is, n=3 orbitals before n=4 orbitals.
What is Ar 4s2 3d8?
Nickel. (Ar) 3d8 4s2.
