Question

The hardness of these minerals is most closely related to the
(1) Mineral’s color.
(2) Mineral’s abundance in nature.
(3) Amount of iron the mineral contains.
(4) Bonding of the mineral’s atoms

Answer 1

Answer:

(4) Bonding of the mineral's atoms

Explanation:

Answer 2

The hardness of minerals has a very close relationship with the internal arrangement of it's atoms (bonding).

• Hardness of a mineral refers to a measure of it's resistance to scratching.
• The color of a mineral does not have any effect on the chemical structure of the mineral.
• Mineral abundance has to do with the amount of the mineral which exists in nature.
• The iron content in a mineral does not necessarily infer hardness
• The bonding of mineral atoms which involves the arrangement of the atoms which the mineral is composed of determines the hardness. The greater the strength of the bonding, the higher the minerals level of hardness.
• The lattice structure and nature of bonding determines how hard a mineral will be. Minerals which exhibits covalent bonding between their atoms with a three dimensional lattice structure are usually harder than minerals which exhibits close lattice packing.
• Hardness can be measured on the moh scale.
