How to solve Q:2

2. y X Figure 1 Figure 1 shows the boundary surface of 2s orbital of a hydrogenic atom in three dimensions. (0) Define boundary surface. (ii) What are the number 2 and the letter s in the name '2s orbital stand for? (iii) Other s orbitals (such as 1s, 3s, etc. orbitals) have similar spherical boundary surfaces. How do you differentiate between the different types of the s orbitals? (iv) By using the separation of variables, the wave function of a particle in a three-dimensional space can be written as an expression w(r,0,0)= R(r)Y(0,0) Explain the changes occurring to this expression for a particle in the s orbital
