The wire as a whole is neutral as it contains both negatively charged electrons and positively charged nuclei. The issue about the battery releasing elecrons into the wire is quite subtle. Though there are local movements of electrons from the negative terminal of the battery into the wire, this is balanced by the movement of electrons from the wire into the battery via the positive terminal of the battery. There is therefore no net movement of electrons into the wire from the battery. | |

I also read in an article that the battery undergoes a chemical reaction in which it creates electrons that it releases into a wire. On the other terminal the battery creates an attraction between electrons. Here is the link: science.org.au/curious/technology-future/batteries | |
