Question

Write the general electronic configuration of d- block elements.

Answer 1

In the given question it is asked about the electronic configuration of the given d-block elements. Now to find it we just have to mention the range and the number we obtain regarding the subshells at the end of the configuration like in this case the number and the range of the electrons in each kind of subshell would give the answer as $(n - 1){d^{1 - 10}}n{s^{1 - 2}}$.

Complete answer:
In the given question we have to find out the step by step analysis of how to find the electronic configuration of the d-block elements.
Now by going step by step we need to specify the process of each acquiring in each step:
Step 1: First of all we need to have a variable value as $n$ which denotes the period to which the element belongs. Now specifically for the case of the d-block, this value of $n$ would vary between $4 - 7$.
Step 2: We have to provide the ultimate range of configuration by giving the ranges of both the d and s subshells in the terms of the $n$ and the number of electrons in each subshell.
For the case of d subshell the number of the shell would be $n - 1$ whereas we know that the number of electrons in the shell can also vary from $1 - 10$, so that would give us a resemblance of $(n - 1){d^{1 - 10}}$.
For the case of s subshell the number of the shell would be $n$ whereas we know that the number of electrons in the shell can also vary from $1 - 2$, so that would give us a resemblance of $n{s^{1 - 2}}$.
Therefore that would make the final answer as the $(n - 1){d^{1 - 10}}n{s^{1 - 2}}$.

Note: In atomic physics and quantum chemistry, the electron configuration is the distribution of electrons of an atom or molecule (or other physical structure) in atomic or molecular orbitals. Electronic configurations describe each electron as moving independently in an orbital, in an average field created by all other orbitals.
