Because Nucleus is composed of protons and neutrons..
I would like to know why you stop heating the sulphuric acid before placing in the copper oxide in making copper sulphate crystals

Visible range of hydrogen spectrum will contain the following series: (1) Pfund (2) Lyman (3) Balmer (4) Brackett Ans: Balmer
a metal forms 2 oxides. the higher oxide has 80% metal. 0.72g of lower oxide gave 0.8g of higher oxide when oxidised. show that law of multiple proportion is valid?
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.
BECAUSE THE REPULSIVE FORCE OF PROTONS IS LESS THAN THE ATRACTIVE FORCE BETWEEN NUCLEONS.
