An atomic model represents the structure of an atom. a) Name two atom models. b) What is the relation between the energy of shells and its distance from the nucleus. c) What is the maximum number of electrons that can be accommodated in N shell?
d) What is the limitation of Rutherford’s atom model.
Answers
Answer:
Although the Rutherford atomic model was based on experimental observations it failed to explain certain things. Rutherford proposed that the electrons revolve around the nucleus in fixed paths called orbits.
this is the answer for d one

Answer:
- the quantum mechanical model of the atom, which treats electrons as matter waves. ... An atomic orbital is defined as the region within an atom that encloses where the electron is likely to be 90% of the time.
- Electron shells and the Bohr model
Each electron shell has a different energy level, with those shells closest to the nucleus being lower in energy than those farther from the nucleus. By convention, each shell is assigned a number and the symbol n—for example, the electron shell closest to the nucleus is called 1n.
3.50
Answer. the maximum no. of electrons can be accommodated in n shell of an atom is 50 because it is made by a formula 2n×n ,n means the no of shell like shell m is 4th shell then 2×4×4=32
4.Limitations of Rutherford Atomic Model
Although the Rutherford atomic model was based on experimental observations it failed to explain certain things. Rutherford proposed that the electrons revolve around the nucleus in fixed paths called orbits.
