Explanation: Copper and Aluminum are good conductors of electricity as they offer low resistance, hence they are used in electric wires. Gold, Platinum and Silver is used to make jewelry as they are less reactive. So, they don't corrode. Copper is less reactive so it doesn't react with hot water. Therefore, it is used in hot water tank. Graphite is the only non-metal that is a good conductor of electricity. So, it is used as electrodes. Metals generally are sonorous (make sound when it hits hard surface). This is the reason why they are used in bells and strings of musical instruments.
