Question

Is platinum stronger than gold?

Answer 1

Hint: Metals are used for a wide application due to their characteristic properties. This fact of metals makes them suitable for making jewelry. Gold and platinum are called transition metals, as they appear in the center of the periodic table, between metals and nonmetals.

Complete answer: Metals have various properties. Some of them are:
- Metals have a lustrous and shiny appearance.
- Malleability, that is they can be molded into thin sheets.
- Ductility, that is metals can be molded into thin wires.
- Metals are hard, and sonorous, that is they create a sound.
- Metals are good conductors of electricity.
The properties of luster, malleability, and ductility make metals suitable for making jewelry. Gold and platinum are transition metals of the d- block. They are also called noble metals due to their use in making ornaments.
Among platinum and gold, platinum is considered to be denser and durable than gold, which makes it more hard than gold. Platinum is heavier than gold, it is more ductile, and can be easily made to wires. Platinum is also resistant to corrosion more than gold. The density which is the mass by volume of any metal makes it more strengthful. Platinum has a density of 21.45 g per cubic cm, while Gold has density of 19.3 gram per cubic cm, which makes platinum more stronger than gold.
Hence, platinum is stronger and harder than gold.

Note: Densities of the metals are their measure of heaviness, so, more dense a metal is, more heavy and stronger it is. Platinum is a more dense metal than gold. But platinum is less malleable than gold, that is it cannot easily be made into thin sheets than gold.
