Question

D-there are five orbital in d-shell, explain.

Answer 1

Answer:

There are five d orbitals, referred to as dz2, dxy, dxz, dyz , and dx2-y2. The d orbitals are what give transition metals their special properties. In transition metal ions the outermost d orbitals are incompletely filled with electrons so they can easily give and take electrons.

Answer 2

The d-sub shell (L=2) have five orbitals called d-orbitals. The individual orbitals are labelled by magnetic quantum number (m) given by 2L+1 so that the value of m will be from -L to +L through zero. Hence , for L=2 , m= -2, -1, 0, +1, +2. Since there are five choices for the magnetic quantum number, it gives rise to five degenerated d-orbitals referred to as dxy, dyz , dzx , dx2-y2, and dz2.

Note that L is actually azimuthal quantum number which governs the shape of the orbital. so when L=2 it is d-orbital.
