Answer 1

Hey mate ,

Here your answer

Hope you understand

Answer 2

Answer : The shape of $d_{z^2}$ orbital is shown below.

Explanation :

As we know that there are many sub-levels which are s, p, d, f, g and so on. The sub-level are oriented in three directions along the x, y and z axis.  

The 's' sub-level has one orbital that are spherically shaped.

The 'p' sub-level has three orbitals $(p_x,p_y,p_z)$ that are dum-bell shaped.

The 'd' sub-level has five orbitals $(d_{xy},d_{xz},d_{yz}d_{z^2},d_{x^2-y^2})$ that are double-dum-bell shaped.

The 'f' sub-level has seven orbitals $(f_{x(x^2-3y^2)},f_{y(x^2-3z^2)},f_{y(3x^2-3y^2)},f_{xz^2},f_{z^3},f_{yz^2},f_{xyz})$ that are complex flower shaped.
