Theory OF plane in 3D

Theory OF Tangent || Theory OF Normal

The electron density in the xy plane in 3d_(x^(2) - y^(2)) orbital is zero

The electron density in the xy- plane in 3d_(x^(2) - y^(2) orbital is zero

Theories OF Organic Evolution || Mutation Theory || Modern Theory OF Evolution (Neodarwinism)

Consider the following statements: (a) Electron density in the XY plane in 3d_(x^(2)-y^(2)) orbital is zero (b) Electron density in the XY plane in 3d_(z^(2)) orbital is zero. (c ) 2s orbital has one nodel surface (d) for 2p_(z) orbital, XY is the nodal plane. Which of these are incorrect statements :

Theory OF Biogenesis || Modern Theory OF Origin OF Life

Number of nodal planes in 3d_(xy) orbital is same as that in :
