complete the sentences below that describe a voltaic cell: in a voltaic cell oxidation occurs at the. this…

Brief Explanations:

In a voltaic cell, oxidation occurs at the anode where atoms lose electrons and become more positive. Reduction occurs at the cathode where atoms gain electrons and become more negative. These are fundamental concepts in electro - chemistry related to redox reactions in electrochemical cells.

Answer:

In a voltaic cell oxidation occurs at the anode. This means that electrons are lost and it becomes more positive. In a voltaic cell reduction occurs at the cathode. This means that electrons are gained and it becomes more negative.
