The sum of the number of lone pairs of electrons on each central atom in the following species is [ T e B r 6 ] 2 - , [ B r F 2 ] + and [ X e F 3 ] - (Atomic number: F = 9, Br = 35, Te = 52, Xe = 54)
Correct answer
6
Step-by-step solution
Species Lone pair on central atom T e B r 2 - 1 B r F 2 + 2 X e F 3 - 3 Total number of lone pair = 6.
