Introduction
Writing an element with the help of symbol
Pre-Requisites:
Atomic number and mass number
Activity:
Almost every element has isotopes. Try finding the atomic mass of elements by the mass of their isotopes and their abundances and then match it with their original atomic mass
Real Life Question:
Can you think of any element with no neutron?
Key Words / FlashCards
| Key Words | Definitions (pref. in our own words) |
|---|---|
| Isotopes Isobars | Atoms with different mass number but same atomic number Atoms with same mass number but different atomic number. |
Learning aids / Gadgets
| Gadgets | How it can be used |
|---|---|
| Make a chart of isobars as they are only a few | Try to remember them |
Real life uses :
Isotopes help us in knowing the exact mass of the elements.
Practical examples around us
| Examples | Explainations |
|---|---|
| The most common one is the 3 isotopes of hydrogen |
What you learn in Theory:
Isotopes and isobars
What you learn in Practice:
Almost every element has isotopes and that helps us in knowing their exact mass.
