Answer 1

$H e$ and $L i^{+}$ have 2 electrons. Isoelectronic species have same spectra.
According to Pauli's exclusion pinciple, two electrons in a shell should have opposite spins.
Only orbitals aligning along the axis participate favourably in the hybridization because they have the same symmetry. Hence, $d_{z^{2}}$ orbitals participate in $s p^{3} d$ hybridization.
