Chemistry - CHEMICAL BONDING Question with Solution | TestHub

$\mathrm{\text{B}}{\mathrm{\text{e}}}_2$-  8 electrons

$\mathrm{\text{σ}}1{\mathrm{\text{s}}}^2{\mathrm{\text{σ}}}^{\mathrm{\text{*}}}1{\mathrm{\text{s}}}^2\mathrm{\text{σ}}2{\mathrm{\text{s}}}^2{\mathrm{\text{σ}}}^{\mathrm{\text{*}}}2{\mathrm{\text{s}}}^2$, bond order is 0.

So it doesn't exist.
