Correct answer: 6

Number of σ -bonds formed by central metal atom/ ion Number of lone pairs on central metal atom/ ion (i) In ⁡ T e B r 6 2 - 6 1 (ii) In ⁡ B r F 2 + 2 2 (iii) In ⁡ S N F 3 4 0 (iv) In ⁡ X e F 3 - 3 3 ⇒ Total number of lone pairs of electrons = 1 + 2 + 0 + 3 = 6

The sum of the number of lone pairs of electrons on each central atom in the following species i s     T e B r 6 2 - ,   B r F 2 + ,   S N F 3   a n d   X e F 3 - [Atomic number : N   =   7 ,   F   =   9 ,   S   =   16 ,   B r   =   35 ,   T e   =   52 ,   X e   =   54 ]
