$P > S$
$Cu < Zn$
$Zr < Hf$
Describe the shapes of $BF $$_{3}$ and $BH _{4}^{-}$. Assign the hybridisation of boron in these species.
$A{l_2}{O_3}$ formation involves evolution of a large quantity of heat, which makes its use in
Given below are two statements:
Statement $I$ : The decrease in first ionization enthalpy from $B$ to $Al$ is much larger than that from $Al$ to $Ga$.
Statement $II$ : The d orbitals in Ga are completely filled.
