Q. Explain Distillation in purification of metals? Metals with low boiling points, such as cadmium, zinc and mercury will be purified by distillation. The distillation is gener
in the nucleus of any atom,the no. of protons and the no. of neutrons are same.Also in the nucleus the protons and the neutrons are intermixed not remain seperated.In nucleus two protons never touch each other because between any two proton there is always a neutron which contradicts the force of repulsion.
