Evidences in Support of Divisibility of Atom: Following observations show that atom is made up of different particles like electrons, protons and neutrons, i.e. atom is divisible:(i) Formation of ionic compounds is possible due to the formation of ions which involves the transfer of electrons.(ii) Presence of isotopes for the same element is possible due to the difference in the number neutrons.

10thMy experience with Abhyas is very good. I have learnt many things here like vedic maths and reasoning also. Teachers here first take our doubts and then there are assignments to verify our weak points.
