Answer:
To have the electronic configuration equal to 1sĀ²2sĀ²2pā¶3sĀ²3pā¶4sĀ²3dā·, the chemical element must have an electrical charge equal to 27, that is, it must have 27 electrons, such as Cobalt (Co), for example.
Explanation:
The electronic configuration shown in the question above is known as the Linus Pauling distribution and represents the energy sub-levels that an electrically charged atom can have in relation to the amount of electrons it has.
The layers sub-levels are presented in the following order 1sĀ² 2sĀ² 2pā¶ 3sĀ² 3pā¶ 4sĀ² 3dĀ¹Āŗ 4pā¶ 5sĀ² 4dĀ¹Āŗ 5pā¶ 6sĀ² 4f14 5dĀ¹Āŗ 6pā¶ 7sĀ² 5f14 6dĀ¹Āŗ 7pā¶. Where the small numbers represent the number of electrons in each sub-level and the large numbers represent the layers of electronic distribution.
Accordingly, we can see that an atom that has the configuration 1sĀ²2sĀ²2pā¶3sĀ²3pā¶4sĀ²3dā· has 27 electrons, like Cobalt.
