Explain diagrammatically the boundary surfaces for three 2p orbitals and five 3d orbitals.

Explanation

Shape of p - orbital : Shape of p -orbital is dumb-bel . There are three 2p - orbitals . They are `2p_(x),2p_(y)and2p_(z)` orbitals . Each orbital has two lobes . These lobes are oriented along their respective axes . Each p orbital has one nodal plane.

Shape of d-orbital : d -orbital has double dumb -bell shape . There are five d-orbit als. They `d_(xy),d_(xz),d_(x^(2)-y^(2)) andd_(z^(2))`.
Each d orbital has 4 lobes . In `d_(xy)` orbital , the lobes are placed in- between the x and y axes, similar is the case with other orbitals, `d_(yz) and d_(xz) . " In " d_(z^(2))` orbital , two lobes lie along z aixs and there is a ring of electron-cloud around the centre. In `d_(x^(2)-y^(2))` orbital , the lobes lie along x and y axes. Each d orbital has two nodal planes.
