4. 5. 5. Describe wave particle duality of electron of De Broglie Hypothesis? What are Limitations of Bohr's Atomic Model? Differentiate between shell and sub shell with examples? How the atoms of O, and are similar or different from each other? Write down the names of sub atomic particles their masses in a.m.u with th unit charges.

Answer:
Wave-particle duality is the concept in quantum mechanics that every particle or quantum entity may be described as either a particle or a wave. This phenomenon has been verified not only for elementary particles but also for compound particles like atoms and even molecules.
The de Broglie hypothesis showed that wave-particle duality was not merely an aberrant behavior of light, but rather was a fundamental principle exhibited by both radiation and matter. ... It is now an integral part of the theory of atomic structure and particle physics.
Shells are a collection of subshells with the same principle quantum number, and subshells are a collection of orbitals with the same principle quantum number and angular momentum quantum number.n an atom, a shell is a collection of subshells with the same principle quantum number,
. The 3s, 3p, and 3d subshells are part of the same shell, as they all have the same principle quantum number of 3. The large is, the further the shell is away from the center, so electrons in the same shell are at a similar distance from the nucleus.
A subshell is a group of orbitals. Subshells are collections of orbitals which share the same principle quantum number and angular momentum quantum number,
