In atoms,electrons and nucleus(proton) attract each other with a force,                                            F= K.q.Q/r 2
K=Proportionality constant
q=Charge on electron(e)
Q=Charge on nucleus(Ze)
 
 
But the centripetal force on electron which equals the electrostatic force between electron and nucleus keeps the electron in circular path.
HENCE,ELECTRONS AND PROTONS DO ATTRACT EACH OTHER TO AN EXTENT.
