1.

The sun of the number of lone pairs of electrons on each centrel atom in the following species is [TeBr_(6)]^(2-), [BrF_2]^(+), SNF_(3) and [XeF_(3)]^(-) (atomic numbers : N=7,F=9,S=16,Br=35,Te=52,Xe=54)

Answer»


Solution :`{:("Species",,"lone pair on central atom"),(TeBr^(2-),:,1),(BrF_(2)^(+),:,2),(SNF_(3),:,0),(XeF_(3)^(-),:,3):}`
Total no. of lone pair =6
`SNF_(3)`:`{:("N"),("|||"),("S"),("/|\"),("FFF "):}`
