Introduction
We discuss the different aspects of three specific allotropes of phosphorous, such as structure, properties and preparation.
Pre-Requisites:
Allotrope, Chemi-luminiscence, Inert, Tetrahedral, Polymeric.
Activity:
The glow in the dark stickers or stars that we all love are made of nothing but phosphorous- probably white phosphorous, since it shows that property.
Real Life Question:
What are our favorite glow in the dark stars made up of?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Chemi-luminiscence | A property of a substance which enables it to glow in the dark. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| 3D structures or toys | To be able to visualize how the structures of the allotropes exist physically. |
| Video aids | To understand the preparation and chemical reactions of the allotropes. |
Real life uses :
To make glow in the dark stickers, to manufacture phosphine, which is used in Holme's signals, and so on.
Places to visit :
The glow in the dark planets and stars that your little sister stuck on her ceiling? They are made up of nothing but allotropes of phosphorous- probably white phosphorous.
Practical examples around us
| Examples | Explainations |
|---|---|
| Glow in the dark stickers | They consist of nothing but phosphorous allotrope. |
What you learn in Theory:
The methods of preparation, properties, chemical reactions and structures of some important allotropes of phosphorous.
What you learn in Practice:
The ways in which these allotropes are used, and how they can be prepared chemically.
