Sub Topic Name : Representation Of Atoms |
|
Introduction
All matter around us is made up of atoms There is a large variety of matter around us therefore each atom should have a unique representation. Dalton used symbols for elements. IUPAC approves names of elements. The representation of atoms helps us to differentiate one element from another.
Pre-Requisites:
Atom, matter
Activity:
Each compound is represented by symbols of the atoms of each element present in the compound.
Real Life Question:
How do you know that the formula H2O represents water?
