- Atoms of different element can also have some similarities.
- According to Eienston, E=MC2. This shows that mass is destructible. i.e., atoms can also be destroyed.
- Atoms of same element may not be identical in all aspects due to the presence of isotopes.
- In some compounds, atoms are formed to be combined in fration.
