Metals like potassium and sodium react vigorously with oxygen and catch fire if kept in open. Hence they are stored in kerosene to prevent burning. If magnesium is heated, it burns with a bright flame. If iron is heated it glows brightly. If copper is heated it does not burn but forms a black coating of copper oxide.
