Within an electron configuration, what do symbols such as [Ne] and [Kr] represent?
Here, we are going to discuss what the given symbols represent in an electronic configuration.
In writing the electronic configuration, an orbital is shown by using its proper symbol.The number of electrons present in an orbital is shown as the right-hand superscript of the symbol of the orbital.
For example, the electronic configuration of hydrogen is 1s1. This means that the single electron in hydrogen occupies the s orbital present in the principal energy level n = 1. Similarly the electronic configuration of other elements are written.
