What is the actual configuration of copper explain its stability?

<br> Copper has the electronic configuration `[Ar]3d^(10)4s^(1)` and not `[Ar]3d^(9)4s^(2)` due the symmetrical distribution and exchange energies of d electrons. <br> Symmetry leads to stability.

Why is gold’s electron configuration different?

Elements want to achieve noble gas configurations, and if they can’t, then they want to have a half-filled orbitals. In the case of gold the d-orbital is filled completely and the s-orbital is half filled. Whereas Platinum doesn’t have that complete d-orbital filled.

### What is the electronic configuration of copper and why it is so?

The atomic number of Copper(Cu) = 29. 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 is the electronic configuration of copper different?

Why is the electronic configuration of CU and CR different? They both hace exceptional configuration. Because half filled and fully filled orbitals are more stable beacuse of symmetry and high exchange energy. That is why Cu have [Ar] 3d10 4s1 in spite of [Ar] 3d9 4s2 and Cr have [Ar] 3d5 4s1 in spite of [Ar] 3d4 4s2.

How do you write the electron configuration of an element?

Writing Electron Configurations. When writing an electron configuration, first write the energy level (the period), then the subshell to be filled and the superscript, which is the number of electrons in that subshell. The total number of electrons is the atomic number, Z.

How many electrons are in gold’s valence shell?

Gold contains 1 electron in its outer shell, thus it has 1 valence electron only.

## How do you explain anomalous electronic configuration of copper?

Solution

1. Copper (Cu) has atomic number 29.
2. Its expected electronic configuration is 1s2 2s2 2p6 3s2 3p6 4s2 3d9.
3. The 3d orbital is neither half-filled nor fully filled. Hence, it has less stability.
4. Due to interelectronic repulsion forces, one 4s electron enters into a 3d orbital.

### What are the characteristics of gold?

Gold Properties

• Gold conducts heat and electricity.
• Gold is ductile: It can be drawn out into the thinnest wire.
• Gold is highly reflective of heat and light.
• Gold is prized for its beauty.
• Gold is malleable, so it can be flattened into extremely thin sheets.

What is electron configuration has the greatest stabilty?

Electron configurations with a duplet or octet structure have the greatest stability. Explain how an atom’s valence electron configuration determines its place in the periodic table? Elements in a given column have the same number of valence electrons. The energy level of an atom’s valence electrons determines its period.

### Which electron configuration is most stable?

The most stable electron configuration is that of a noble gas, due to the fact that its valence shell is filled. For helium, that means two valence electrons (a duet) in the 1s sublevel, and for the rest it means eight valence electrons (an octet) in the outermost s and p sublevels.
