Which is a non-metal mineral? iron aluminum copper gypsum

gypsum

Gypsum is a non-metal mineral.

To determine which is a non-metal mineral among the options given, you would need to understand the properties of metals and non-metals.

Metals are typically shiny, malleable, ductile, and good conductors of heat and electricity. Non-metals, on the other hand, are generally dull in appearance, brittle, poor conductors of heat and electricity, and have lower densities.

Analyzing the options:

1. Iron: Iron (Fe) is a metal and is commonly known for its strength and magnetic properties. It does not fit the description of a non-metal.

2. Aluminum: Aluminum (Al) is also a metal. It is lightweight, corrosion-resistant, and is widely used in various applications. Like iron, aluminum does not qualify as a non-metal.

3. Copper: Copper (Cu) is yet another metal with excellent electrical conductivity and high ductility. Therefore, it is not a non-metal.

4. Gypsum: Gypsum is a naturally occurring mineral and, unlike the previous options, it falls under the category of non-metals. It is a soft, white, and translucent mineral composed of calcium sulfate dihydrate. Gypsum is widely used in construction, including making plasterboard and fertilizers.

In conclusion, among the options provided, gypsum is the non-metal mineral. Remember to consider the properties of metals and non-metals when making such determinations in the future.
