# why in atom electrons and protons do not attract each other whether they carries positive and negative charge?

Sun January 01, 2012
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.

# Q) In an atom the maximum number of electrons in the outermost shell is 8 and the electrons cannot be furthur placed in a new shell unless the previous shell is filled completely. Then the maximum number of electrons in the third shell should be 8 ,as it becomes the outermost shell at that time because unless it is filled completely only then electrons can be fitted in the next shell. Then how (2n)square rule is correct? according to it the maximum number of electrons should be 18???Please can you solve my query???
