We are all human beings. We are all living beings. Our body is approx 70% water. Water is H2O. Our lung is full of air. Air is N2, O2, CO2.. . Bones are mostly calcium(Ca). So our body is made of natural elements as enlisted in the Periodic Table. These natural elements are made of molecules. Molecules are made of atoms. Atoms are made of electron, proton and neutron. Electrons of water are same with electrons of air or bones. So, we can say our body basically is made of electron, proton and neutrons.These electron,proton and neutrons can not move on their own. When we move our hand or any other limbs; so many electron,proton and neutrons will be moved. So, who are we? Are we all these electrons, protons and neutrons or something else which is able to move these particles.
