The document discusses various atomic models, including Rutherford's discovery of the nucleus and Bohr's proposal of discrete energy levels for electrons. It highlights the differences between Rutherford's and Bohr's models, specifically regarding electron orbits, and describes Schrödinger's electron cloud model as the most advanced representation of atomic structure. The importance of these atomic theories in shaping modern science, including chemistry and nuclear energy, is also emphasized.

1. • Rutherford described the
atom as having a tiny,
dense, and positively
charged core called the
nucleus. Rutherford
established that the mass of
the atom is concentrated in

4. • He proposed that energy
levels of electrons are
discrete and that the
electrons revolve in stable
orbits around the atomic
nucleus but can jump from
one energy level (or orbit) to

7. What are the similarities between
Rutherford and Bohr atomic model?

8. Bohr's model of the atom is similar to
Rutherford's model in that they both have a
nucleus with protons in it and the electrons
surrounding the nucleus.

9. What is the difference between
Rutherford and Bohr atomic
model?

10. The main difference between Bohr model
and Rutherford model is that in
Rutherford model, electrons can revolve in
any orbit around the nucleus, whereas in
Bohr model, electrons can revolve in a
definite shell.

11. • Schrödinger combined the
equations for the behavior
of waves with the de Broglie
equation to generate a
mathematical model for the
distribution of electrons in
an atom.
1926
ERWIN SCHRÖDINGER

13. The electron cloud model is currently the most
sophisticated and widely accepted model of the
atom. It retains the concept of the nucleus from Bohr
and Rutherford's models, but introduces a different
definition of the motion of electrons around the
nucleus.

15. How important is the
contribution of different atomic
theories to our modern model
of the atom?

16. Atomic theory established that all matter
is made of tiny particles, a discovery that
led to amazing scientific breakthroughs
in areas from modern chemistry to
nuclear energy.
