Nucleus

Nucleus is a centre of an atom. It is a positively charged element of an atom. Nucleus consists with positively charged proton and charge nutral neutron. Hence, it belongs positive charge. 

In Rutherford atomic model it termed as positively charged. The entire mass of an atom is concentrated into nucleus. 

How number of proton consists in nucleus same number of negatively charged electron revolves surrounding nucleus. 

When difference of charge between nucleus and electron is found then atom converts into Ion. 

Rapid speed of motion of electron that is revolving surrounding nucleus is not getting displaced or collapsing. This is a result of electrostatic force between electron and nucleus. Two electrostatic force excerts here is called centrifugal force and centripetal force which are same.
