उत्तर
The given sentence is right.
Explanation:
- Both sodium (Na) and magnesium (Mg) have electrons in their K and L shells; specifically, their K shells are filled with 2 electrons and their L shells are filled with 8 electrons.
- While they also have electrons in their M shells (1 and 2, respectively), it is factually accurate to state that the K and L shells contain electrons.
