Jan 17, 2017 · Now copper has two oxidation numbers $+1$ and $+2$ and as copper is d-element of the $4$ period it follows the $18$-electrons rule. But probably the $18$ electrons aren't created to …

Sep 9, 2022 · Closed 3 years ago. I understand that copper has the electronic configuration $\ce { [Ar] 4s^1 3d^10}$ because a fully filled $\ce {4d}$ orbital provide a more stable configuration. But I don't …

Apr 29, 2012 · In the case of copper, the $\mathrm {3d}$ -orbital has dropped in energy below that of the $\mathrm {4s}$, so that it is better to have the paired electrons in the $\mathrm {d}$ and the unpaired …

Jan 31, 2022 · In chromium, having a $4s^2$ $3d^4$ configuration results in electron-electron repulsion due to the two electrons in the $4s$ orbital. For this reason, chromium adopts a $4s^1$ $3d^5$ …

2 Chromium and copper are examples of elements with "anomalous" electron configurations, meaning that they don't follow the normal rules we use for populating the configurations of other elements. …

If I use (a), the electron configuration of copper is $ [Ar] 3d^ {9} 4s^2$ and which isn't stable. But if I use quantum numbers in (b), it is the same with the last electron of zinc.

The electron configuration of copper is 1s 2 2s 2 2p 6 3s 2 3p 6 4s 1 3d 10. If we followed the general pattern of filling electron orbitals, we would have... See full answer below.

The common charges of an element can be related to the electron configuration of the element. Why would copper ions have two common charges? Explain each of them in terms of the electron …

Jul 26, 2015 · In chromium and copper, the are the configuration fill up like $$\\mathrm{3d^5 4s^1}$$ but not $\\mathrm{4s}$ first as it has lower energy level. and why only these 2 elements.

The electronic configuration of an element gives us clear details of the chemical and physical properties of the element. Answer and Explanation: 1 Copper is a very useful metal. It is a good conductor of …
