If the electronic configuration of an element is 2, 8, 2, to which period of the Modern Periodic Table does it belong ?
If the electronic configuration of an element is 2, 8, 2, to which period of the Modern Periodic Table does it belong ?
The electronic configuration of 2, 8, 2 corresponds to the element’s distribution of electrons across its shells. Here, the outermost shell (which is the third shell) has 2 electrons.
This configuration indicates that the element is in the third period of the Modern Periodic Table.
