Yes, Absolutely......... Gold is softer than Iron... Gold becomes Harder because of other components that is being added like Silver and Copper. They add these components to add strength into the Jeweleries.
Because it was lighter, harder, and more durable than iron
Cobalt is harder than iron yet melts at a lower temperature and is somewhat heavier.
Iron Ranks about a 4-5 on the Moh's hardness scale. A diamond is a perfect 10 diamond. A diamond much harder then iron.
i believe that iron is a mineral
false a mineral can not scratch any mineral harder than itself
false. if a mineral is harder than another mineral, it would be able to scratch the softer one
it is iron

Yes. Diamond.
The mineral fluorite is harder than calcite. Fluorite is represented as a 4 on the Mohs scale of relative mineral hardness, calcite is a 3.
calcite
Iron is generally harder than bronze, but variations in chemistry or impurities can vary the hardness in both materials.
yes
Yes.
No, there is no correlation between color and hardness in minerals.
If you mean isn't harder than quartz but harder than apatite ( you spelled it wrong), that would be Orthoclase Feldspar. Else the minerals that are harder than both apatite and quartz are topaz, corundum, and diamond (diamond being the hardest, well the hardest non synthetic mineral).
