Introduction
Why did rutherfords model of atom fail ?
Pre-Requisites:
Rutherfords model
Activity:
Change of direction also causes acceleration. Find out what other factors led to another model ie bohr’s model of atom
Real Life Question:
How does the atom destroy itself if believed to be like the solar system?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Rutherfords model leading to destruction of atom | Moving electron gets accelerated & loses energy due to which eventually nucleus pulls it and the atom gets destroyed |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|
Real life uses :
This led to the bohr’s model of atom that is still in use today
Places to visit :
Visit a circus and see the death well show
Practical examples around us
| Examples | Explainations |
|---|---|
| the death well in circus | Here also acceleration is due to change of direction |
What you learn in Theory:
Drawbacks of rutherfords model
What you learn in Practice:
Acceleration can be due to change of direction also
