Question

Rutherford&#8217;s experiments on scattering of alpha particles proved that:a)atoms contain electronsb)number of positive charges is equal to the number of negative chargesc)atom is mostly emptyd)positive charge is uniformly distributed in the atomCorrect answer is option 'C'. Can you explain this answer?

Answer

While conducting the experiment He noticed that most of the α-particles passed through the foil undeflected, while some deflected at very large angles.
This exp proved that' most of the space in the atom is EMPTY 'and the positive charge is concentrated into a small space called nucleus...
Thus c is the ans...

Answer

Most of the α-particle passed through the foil straight without suffering any change in their direction. This shows that most of the space inside the atom is empty or hollow.
A small fraction of α-particles was deflected through small angles and a few through larger angles. For this to happen α- particles (positively charged) must approach a heavy positively charged core inside the atom (like charges repel each other). This heavy positively charged core inside the atom was named as the nucleus.

Answer

Rutherford's Alpha Particle Scattering Experiment
Rutherford's experiments conducted in 1909 were pivotal in reshaping our understanding of atomic structure. By directing alpha particles at a thin gold foil, he made groundbreaking discoveries about the atom.
Key Observations
- Deflection of Alpha Particles: Most alpha particles passed straight through the foil, but some were deflected at large angles, and a few even bounced back.
- Surprising Results: The unexpected deflections indicated that the positive charge and most of the mass of the atom were concentrated in a very small region.
Conclusion: Atom is Mostly Empty
- Atomic Structure: The results led to the conclusion that atoms consist largely of empty space. If they were solid, the alpha particles would not have passed through with such ease.
- Nucleus Discovery: The concentrated positive charge suggested the existence of a small, dense nucleus at the center of the atom, surrounded by electrons. This was a significant departure from the previously held 'plum pudding' model, where the positive charge was thought to be evenly distributed.
Significance of the Findings
- Foundation for Modern Atomic Theory: Rutherford's work laid the groundwork for the Bohr model of the atom, which accurately describes electron arrangements and energy levels.
- Understanding Atomic Interactions: Recognizing that atoms are mostly empty has crucial implications for fields like chemistry and physics, influencing how we understand molecular formations and reactions.
In summary, Rutherford's alpha particle scattering experiment demonstrated that atoms are mostly empty, containing a tiny, dense nucleus, which revolutionized the concept of atomic structure.

Answer

As we know that in vacuum their are luminiferus ether particles are present ,when we incidence any ray or light through vacuum the ray disturb the ether particle and hence the ether particle provide his won wavelets ,which are known as primary wavelets, and hence process is gone forward

Answer

By this experiment he show most of the space is empty in an atom positive charge concentrated in the centre which is nucleus and electron posses negative charge revolving around nucleus
