Among the minerals listed, talc is the softest, but if we consider only the ones mentioned—albite, biotite, orthoclase, quartz, and granite—biotite is typically the softest. On the Mohs scale, biotite has a hardness of about 2.5 to 3, while albite and orthoclase are harder at 6 and 6-6.5, respectively, and quartz is even harder at 7. Granite, being an igneous rock composed mostly of quartz and feldspar, is much harder than any of the individual minerals listed.

Which lists the minerals in the correct order from softest to hardest?

The correct order of minerals from softest to hardest, based on the Mohs scale of mineral hardness, is talc (1), gypsum (2), calcite (3), fluorite (4), apatite (5), orthoclase feldspar (6), quartz (7), topaz (8), corundum (9), and diamond (10). Each mineral is rated according to its ability to scratch others, with talc being the softest and diamond the hardest.

What lists the minerals in the correct order from softest to hardest?

The hardness of minerals is commonly ranked using the Mohs scale, which lists them in order from softest to hardest as follows: talc, gypsum, calcite, fluorite, apatite, orthoclase (feldspar), quartz, topaz, corundum, and diamond. Talc is the softest mineral, while diamond is the hardest. This scale helps in identifying minerals based on their resistance to scratching.
