Electrons flow into the positive side of the battery, and the electrons are the entities that "flow" from copper atom to copper atom when a circuit is completed around the battery (assuming the conductor is copper).
That's how it's easiest to visualize.
BUT, in electrical engineering the convention, or definition of current flow is that of positive charge, not electron flow. Basic formulas and "laws", such as Maxwells equations (Ampere's law, Gauss' law), Ohms law, Thevanin's and Nortons theorems, and all the others are written taking into account positive charge current flow, not electron flow.

If the current flows from A to B that means the electrons flow from B to A. In general the negative charges from the Battery negative terminal travels through a wire or so and fills the holes in the battery Positive terminal. ( Positive we always mean holes and the free electrons from the negative terminal , being attracted, reaches the holes , less count in the outermost orbit, in molecule, Atom)

Electron have a negative charge always. In a molecule the electron is always looking for a a positive position. When a molecule with 12 electrons comes in contact with a molecule with 9electrons that electron is going to want to jump over the the other one.
Same goes with electricity. You have to think of these on a molecualr level. Neg flows to positive.

nope never...
electric current flows from +ve to -ve terminal
....opposite to the flow of electrons..
ie they flow from negative to positive( from region of higher concentration to region of lower concentration)
