1.	For an orbital in `B^(+4)` radial function is : `R(r ) = (1)/(9sqrt(6))((z)/(a_(0)))^((3)/(4))(4-sigma)sigma e^(-sigma//2` where `sigma = (Zr)/(a_(0))` and `a_(0)=0.529Å,Z` = atomic number, `r=` radial distance from nucleus. The radial node of orbital is at distance from nucleous.A. `0.529Å`B. `2.12Å`C. `1.06Å`D. `0.423Å`
Answer» For radial node `[R(r )]=0` `sigma =4 = (Zr)/(a_(0))" "implies(4a_(0))/(Z)=(4xx0.529Å)/(5)=0.423Å`
