Find the oxidation number of the element underlined in the following s

1.	Find the oxidation number of the element underlined in the following species, underline(Si)H_4,underlineBH_3,BF_3,underlineS_2O_3^(2-),andunderlineHPO_4^(2-)
Answer» SOLUTION :Si=-4in `SiH_4`,B=-3 in `BH_3,B=+3` in `BF_3,S=+2` in `S_2O_3^(2-)`, andP=+5 in `HPO_4^(2-)`
