Question

Number of valence electron in CI ion are (1) =16 (2)=8 (3)=17 (4)= 18 mcq​

Answer 1

Number of valence electrons in Cl ion are 7

atomic number of chlorine is -->> 17

Answer 2

Answer:

None of the options are correct

Explanation:

As Chlorine has an atomic number of 17.

We know that

In a non-metal number of valence electrons is=

8 – Total number of electrons present in last shell

In this case Chlorine has 7 electrons

so 8 – 7

= 1
