If internuclear distance between `A` atoms in `A_(2)` is `10 Å` and between `B` atoms in `B_(2)` is `6Å`, then calculate internuclear distance between `A` and `B` in `Å` [Electronegativity difference between `A` and `B` has negligible value].

Answer

8

Explanation

`r_(A)+r_(A) =10 Å ..(i)`
`r_(B) +r_(B) = 6Å …(ii)`
(i) +(ii)
`2(r_(A)+r_(B)) = 16Å`
`r_(A) +r_(B) = 8Å`
