04. Modification of Dalton’s Atomic Theory

(Present Status of Dalton’s Atomic Theory)

  • Atoms  are no longer considered as indivisible particles. Since sub-atomic particles like electron, proton, neutron etc. are present in atoms.
  • Atoms of same element may not be identical in all aspects due to the presence of isotopes.

  • 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.

Eg. Zn 0.98 O
