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.

A. How many emission lines are possible considering only
these five quantum levels?
n = 5
kn=D4

C. The emission line having the longest wavelength
corresponds to a transition line from the level with
to n=
n =
n = 1
D. The emission line having the shortest wavelength
corresponds to a transition line from n =_to n=_.
