b) 8
c) 17
d) 18​

Answer 1

Answer:

B ) 8

number of valence electrons in C1

Answer 2

Answer:

★ Question : Number of valence electrons in Cl− ion are -

★ Answer : 8

★ Explanation : The electronic configuration of Cl is 2,8,7. This shows that it has 7 electrons in the outermost shell i.e. 7 valence electrons. To form Cl− , it gains one electron. Hence, number of electrons in the outermost shell (valence shell) = 7+1 = 8 .

So, 8 is the correct answer.
