Chemistry - CHEMICAL BONDING Question with Solution | TestHub

The dimer of BeCl₂ exists as Be₂Cl₄, featuring two terminal and two bridging chlorine atoms. Each terminal chlorine atom has 3 lone pairs, while each bridging chlorine atom (forming two bonds) retains 2 lone pairs. The total number of lone pairs in the molecule is $(2\times 3)+(2\times 2)=10$. As requested, the sum of the digits of 10 is $1+0=1$.
