- Copper have A r 3 d 10 4 s 1 electron configuration. And Zinc have A r 3 d 10 4 s 2 electron configuration. My question is, what is the right quantum numbers of last electron of copper?
- The atomic number of each element increases by one, reading from left to right. Block Elements are organised into blocks by the orbital type in which the outer electrons are found. These blocks are named for the characteristic spectra they produce: sharp (s), principal (p), diffuse (d), and fundamental (f).
How many unpaired electrons are in a copper atom?

The electron configuration of copper is
A 5.00A current runs through a 12 gauge copper wire (diameter 2.05 mm) and through a light bulb. Copper has8.5.10^28 free electrons per cubic metre. A) How many electrons pass through the light bulb. A copper ion with a charge of + 2 has 29 protons and 27 electrons. The atomic number of an element is equal to the number of protons in the nucleus of each atom of that element. As one Copper atoms contributes one free electron. Thus number of free electrons N e = N C u = 8. 4 × 1 0 2 2 electrons per c m 3 Answer verified by Toppr.
An unpaired electron is an electron that occupies an orbital of an atom singly, rather than as part of an electron pair (paired electrons means all two spin states of the orbital specified by three quantum numbers n, l and m are fully occupied by two electrons).
To find out if the electrons inside an orbital are paired or not you need to find out the maximum electrons the subshell can hold. If the electrons in the subshell are less than the maximum electrons it can hold the electron in any of the orbital can be unpaired.
There is only 1 orbital in a s subshell . As an orbital can only hold 2 electrons a s subshell can hold a maximum of 2 electrons
Therefore the orbital in the 4s subshell is unpaired.
There are 3 orbitals in p subshell.
For p subshell the maximum electrons is 6. All the p subshells in this atom are full therefore no electron is unpaired.
Number Of Electrons In Copper Ion
There are 5 orbitals in d subshell
And for d subshell the maximum number of electrons is 10. There is only one d subshell in the copper atom and it is full.
Copper has only one unpaired electron
