A new model of the atom was proposed by Neils Bohr in 1913 that electrons are arranged in concentric circular orbits around the nucleus.

This model is patterned on the solar system, called as the planetary model.

Atom no longer considered to be indivisible .
it is divisible into electron proton and neutron

atom of the same element may have different atomic mass e.g. atom of hydrogen may have atomic mass 1 amu ,2 amu , 3 amu


Atom of different elements may have same atomic mass e.g.  calcium & argon have same atomic mass 40

the ratio in which the different atoms combine with one another may be fixed and integral but may not always be simple
example ....C12H22O11 is 12:22:11   which by no means is simple

Atom is the smallest particle that takes part in a chemical reaction

atom is no longer indestructible   atom of nitrogen can changed into oxygen by bombardment of  alfa rays
