diamond
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.
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.
No, iron is harder than potassium. Iron is a metal with a higher Mohs hardness rating than potassium, which is a soft alkali metal.
Sodium is more malleable than iron. Sodium is a soft metal that can be easily cut with a knife, whereas iron is a harder metal that is less malleable.
Platinum is slightly harder than iron and iron can easily scratch gold. Platinum is also the least reactive metal and may have been used by early man before copper.
false a mineral can not scratch any mineral harder than itself

it is iron
Yes. Diamond.
Iron is generally harder than bronze, but variations in chemistry or impurities can vary the hardness in both materials.
It would have to be 5.0 because glass has a hardness of 5.5 and an iron nail has the hardness of 4.5
yes
Yes.
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).
an iron bar is harder to bend.
No, there is no correlation between color and hardness in minerals.
