$\huge{ \underline{\boxed{\red{ \color{red}{\textsf {\textbf{An}{\color{blue}{\textbf {\textsf{sw}}{\color{green}{\textbf{\textsf{er}}}{\color{orange}{\textsf{\textbf{~:-}}}}}}}}}}}}}$

Dalton's atomic theory :

1. Atoms are indivisible particles .
2. Atoms can neither be created nor destroyed .
3. The atoms of an element are alike in all respects but they differ from the atoms of other elements
4. Atoms of elements combine in small whole numbers to form molecules .

Modern atomic theory :

1. Atoms are divisible into sub atomic particles like protons electrons and neutrons .
2. Atoms can be created and destroyed by nuclear fusion and fission .
3. The atoms of an element may not be alike in all respects as is seen in the case of isotopes .
4. In the formation of organic compounds the numbers can be very big such as thousands .
