Introduction
Bohr’s postulates state that: • The electron in the hydrogen atom can move around the nucleus in circular paths called orbits or energy states. • The radius and energy for these circular paths are fixed and are arranged concentrically around the nucleus. • The stationary states have principle quantum numbers. • Electron moved from lower stationary state to higher when energy is absorbed and reverse when energy is emitted.
Pre-Requisites:
Wave, atom
Activity:
Each element has an atom. The atoms combine to make compounds and molecules.
Real Life Question:
How are electrons distributed around the atom?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Atom | An atom is the smallest unit of an element. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Racing track | Picture the atom to be similar to a racing track. The individual concentric tracks are the orbits and the middle ground is the nucleus whereas the athletes are the electrons. |
Real life uses :
Atoms make up molecules.
Places to visit :
Racing track, stadium.

What you learn in Theory:
Bohr’s postulates state that The electron in the hydrogen atom can move around the nucleus in circular paths called orbits or energy states. The radius and energy for these circular paths are fixed and are arranged concentrically around the nucleus. The stationary states have principle quantum numbers. Electron moved from lower stationary state to higher when energy is absorbed and reverse when energy is emitted.
What you learn in Practice:
The atomic structure is important to know the structure of the molecule.
