Protons have positive charge. Electrons have negative charge.so why doesn`t the electrons surrounding the nucleus are not attracted to the protons.

In structure of atom nucleus is surrounded by revolving electrons. Nucleus is positively charged because of positive protons and neutrons being neutral do not contribute in charge.Electrons revolve around the nucleus carry negative charge,so because of positively charged protons and negatively charged electrons there is strong electrostatic force of attraction between them and there is hold of nucleus on electrons.Thus force of attraction works between protons and electrons.But as the size of nucleus is very very small not all the electrons which revolves are equally attracted towards the nucleus.
