Metal And Its Compounds — Part 1 MCQs with Explanations

Tungsten is the hardest metal among the given options. It has the highest melting point (about 3422°C) of all pure metals. Its hardness and ability to withstand high temperatures make it widely used in the production of electrical filaments, cutting tools, and rocket engine nozzles. Gold is a soft metal, Iron is relatively strong but not the hardest, and Platinum is dense and corrosion-resistant but not as hard as Tungsten. Therefore, the hardest metal is Tungsten .
