Q.1(a) What were the important advance (s) as a result of which, idea of an electron orbit movement was swapped by, the notion of probability of finding electron in an orbital? What name was given to the transformed atomic model? Also explain its various postulates. (b) Which quantum numbers revel information about the shape, energy, orientation, and size of the orbitals? How many orbitals are possible for n=4? Which of these may be described as gerade? (c) The signs of the unsquared wave functions are usually shown in plots of the squared functions. Why do you think this practice exists? Give values of angular nodes and plane of 3p, 4d, 2p, 4f, 4s.
Atomic Structure
The basic structure of an atom is defined as the component-level of atomic structure of an atom. Precisely speaking an atom consists of three major subatomic particles which are protons, neutrons, and electrons. Many theories have been stated for explaining the structure of an atom.
Shape of the D Orbital
Shapes of orbitals are an approximate representation of boundaries in space for finding electrons occupied in that respective orbital. D orbitals are known to have a clover leaf shape or dumbbell inside where electrons can be found.
