Concept explainers
(a)
Interpretation:
The Lewis structure for chlorine and its ion has to be drawn.
Concept Introduction:
Lewis structure: This is only way to show the sharing of electrons between atom in polar covalent bonds or covalent bond. This is often called Lewis structure. This structure denotes valence electrons of an atom by dots and also it shows the way of valence electron distributed within a molecule.
