In the molecular orbital diagram for the molecular ion, N₂⁺, the number of electrons in the $$\sigma $$_2pz molecular orbital is :

A sample of $$NaCl{O_3}$$ is converted by heat to $$NaCl$$ with a loss of $$0.16$$ $$g$$ of oxygen. The residue is dissolved in water and precipitated as $$AgCl.$$ The mass of $$AgCl$$ (in $$g$$) obtained will be : (Given : Molar mass of $$AgCl=143.5$$ $$g$$ $$mo{l^{ - 1}}$$)

The decreasing order of bond angles in BF₃, NH₃, PF₃ and I₃^- is :

The correct combination is :
