Solution
Valence electrons of chloride ion:
- The single chlorine atom has 7 valence electrons.
- As the chlorine forms a chloride ion, there is an addition of an electron which enters the atom.
- This makes the valence electron count of the chloride ion to be (7+1) = 8 electrons.
Final Answer: Number of valence electrons in Cl− ion are:
(a) 16
(b) 8
(c) 17
(d) 18
