if i connect positive end of a battery to the negative end of another battery without completing a circuit will electrons flow if not then why

hiii priya 

electron or charge need a path to travel and in this case circuit is not complete , so electrons will not flow in this case . the current always enters from +ve terminal and leaves at -ve terminal. in the battery which has negative polarity , current will flow from +ve to -ve . but this has no meaning because circuit is not complete , hope this will clear .. plz aproove

good luck
