Introduction
• Elements belonging to Group 13 to 18 are p-block members, (noble gases, halogens and chalcogens) • The outermost electronic configuration varies from ns2np1 to ns2np6 in each period. • At the end of each period is a noble gas element with a closed valence shell ns2np6 configuration.
Pre-Requisites:
Element, periodic properties, classification, electronic configuration, shells, orbital
Activity:
Objects with similar usage or characteristics fall in the same group.
Real Life Question:
Why do certain things have similar characteristics?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Electronic configuration | The distribution of electrons into energy levels of an atom is called the electronic configuration. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| A periodic table | Check out the arrangement of elements in the periodic table. |
Real life uses :
Things are classified and grouped according to similar properties between them.
Places to visit :
A classroom, kitchen, garage
Practical examples around us
| Examples | Explainations |
|---|---|
| Tools | Tool used for eating (spoon) is found in the kitchen whereas a hammer is found in the garage or inside toolbox in the storeroom. Similarly elements with similar behavior are groups in the same level. |
What you learn in Theory:
• Elements belonging to Group 13 to 18 are p-block members, (noble gases, halogens and chalcogens) • The outermost electronic configuration varies from ns2np1 to ns2np6 in each period. • At the end of each period is a noble gas element with a closed valence shell ns2np6 configuration.
What you learn in Practice:
Objects grouped into categories have similar properties.
