Question
Which of the following have same electronic configuration?
- Mg+2 , Na+
- Ne, C-4
- S-2 , Cl-
- All the above
Hint:
All the atoms which have the same number of electrons distributed through orbitals will have the same electronic configuration.
The correct answer is: All the above
- The electronic configuration is represented by the number of electrons distributed in all the orbits of an atom
- It may vary according to the atomic number of atoms
- As Mg+2, Na+, Ne, C-4, and S-2, Cl- all have the same number of electrons, their electronic configuration is the same.
