Proton and neutron do not participate in chemical reaction.

Answer 2

Hey friend here is your answer.....


Answer :-


Option 4) electrons is correct.


✺The electrons of the atom is involved in Chemical reactions.


Notes :-

❀ Electrons are discovered by J.J.Thomson in the year 1897 .

❀ Electrons are negatively charged .

❀ Sir. J.J. Thomson concluded that the particles constituting cathode rays are universal constituent of all atoms . These particles be named electrons in 1897 .

❀ Relative charge and mass :

The charge on an electron is taken as a unit of negative charge . So and electron is said to have a charge of -1 unit . The mass of an electron is about 1 / 1840th of a hydrogen atom and so it is treated as negligible .
