2 days ago · b. PBr3 Phosphorus can make hypervalent compounds, but in this specific example it is sharing three bonds and has one lone pair, so it has simply a full octet. SF6 has a sulfur atom surrounded by 6 fluorine atoms, PBr5 has a phosphorous atom surrounded by 5 bromine atoms, and XeF6 has a xenon atom surrounded by 6 fluorine atoms, all of which are hypervalent because there are more than four ...
