Periodic Table
A very useful way of arranging the elements in a table developed by scientists is called the Periodic Table.
A substance made of only one kind of atom is called an element.
The smallest units of an element are called atoms.
Chemical symbols
Each of the elements in the periodic table has a symbol.
Some of the elements have single letter symbol and others have two letters in their symbols.
For single lettered symbols, first letter of the name is used and it is written in capital.
For two letter symbols, the first letter is written in capital and the second in small letter.
