Pure iron is relatively soft and easily worked (malleable). Iron heated to high temperatures and alloyed with carbon and other elements is called steel, which can be made extremely hard and durable, but not easily worked.
No, iron is harder than potassium. Iron is a metal with a higher Mohs hardness rating than potassium, which is a soft alkali metal.
Zinc is considered a hard metal; its hardness is similar to that of Iron.

Gold is considered a relatively soft metal. It has a Mohs hardness of about 2.5 to 3, which means it can be scratched easily compared to harder metals like iron or steel.
It's actually a rather difficult question to answer as iron can be forged in a number of different ways, each giving a different hardness. I've attached a link to a site giving different hardness values for some treatments of grey iron.
Alkali earth metals are relatively soft compared to transition metals, like iron or copper. They can be cut with a knife due to their low hardness.
No, sulfur cannot be easily scratched by a nail because it is a relatively soft material compared to metals like iron or steel. Sulfur has a Mohs hardness of 1.5–2, while iron nails typically have a hardness of 4-5 on the Mohs scale.
no, aluminum is softer.
Zinc is considered a relatively soft metal compared to others like iron or steel, but it is not as soft as metals like lead or tin. It has a Mohs hardness of about 2.5 to 3, which means it can be scratched more easily than harder metals. Zinc is often used in alloys, such as brass, to improve its overall hardness and strength.
For example talc is very soft.
Soft iron gasket material is typically composed of low-carbon steel with a high iron content, usually around 99%. This type of gasket material is known for its malleability and ability to conform to irregular surfaces, making it ideal for sealing applications where flexibility is required.
Talc is the softest mineral and has a hardness of one on the Mohs Hardness Scale. Talc contains silicate and magnesium along with silica and oxygen.
