    Is it an ionic bond or covalent bond?

    I'm in chem and wasn't paying much attention while we did our lab so now I need to write an essay about the lab and have got half of it done (intro and first body) but now i need the scientific explanation.

    We used sodium hydroxide, zinc, pennies, and a bunsen burner to make brass pennies.

    Any help?

    I know this but I'm going to have to find my old Science notes from high school. I would have studied this during my final year so it won't be to hard to find those notes!

    beyond the fact that they are on the opposite spectrum - zinc negative charged, copper positive - I honestly thought it was a Dative bond... I could be totally wrong. been some years since college.

    that may help.

    it probably is ionic, but ionic is normally nonmetal-metal, not metal-metal.

    That's good! Just found my notes and didn't find the answer to your question. Anyway it did say Brass is made up of 65% Copper & 35% Zinc. That's my science lesson for the day!
