Answer :
The electronic configuration 1s2,2s2,2p6,3s2 belongs to Magnesium.
- Electronic configuration depicts the filling of electrons in the subshell and predicts the properties of the elements.
- The electronic configuration has two electrons in the outermost shell which depicts the alkaline earth metal group.
- Checking from the periodic table we get the element as magnesium.
- The distribution of electrons in an element's atomic orbitals is described by the element's electron configuration.
- Atomic electron configurations are represented via a common notation in which all atomic subshells that contain electrons (with the number of electrons written in subscript)
- Uses for electron configurations include: figuring out an element's valency, predicting a set of components' qualities (elements with similar electron configurations tend to exhibit similar properties).
- It also helps in analyzing atomic spectrum data.
