Pupils can then try the 'quiz time' questions to test their metal knowledge. Zinc is also needed for the senses of smell and taste. ionic bonding is the bonding of ions ions are atoms that have charges so if you have bonding between metals and non-metals, you'll get a charged bond because one receives a negative charge (the electron) and the other gets its negativity taken away (via its election being transferred to the non-metal). This may have been accidental at first, owing to the similarity in colour and flame colour between the bright green copper carbonate…. Copper maximizes the performance of the products that contain it, helping save energy, CO 2, money and lives.
