As it makes no sense to talk of hardness when a metal is liquid all values are when the metal is solid. Mercury is 2-2.5 when solid.
In making this table I didn't look-up the hardness of absolutely every metal so some rearrangements maybe be necessary here.

Metals are hard and dense. Categories of metals include basic, earth, alkaline, transition, alkali, and rare. A list of hard metals will include cobalt and tungsten.
carbon steel, wrought iron, stainless steel,cast iron
Chromium is the hardest metal - on the Mohs scale 8,5.
For other metals see the link below.
Iron

what are the characteristics of metals? metals? non-metals?
Metals (as opposed to non-metals and semi-metals) or solids (as opposed to liquids and gases). There could possible be more answers as your questions is not very specific.
Non-metals are located on the right side. Transitional metals in the middle area.
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
The metals that are known to be soft are alkali metals. A couple of these metals include potassium and sodium. They are so soft that they can be easily cut through with a knife.
a scale that ranks ten minerals from softest to hardest
Well, there really is no thin metal. They can be as thick or thin as you want it to be. But the softest (or one of thE) metals would be gold.
The softest land animal is Chinchilla. The rodent is named after the Chincha people of Andes mountains in South America.
Ten metals are platinum, GOLD, Silver, Tin, Mercury, Cobalt, Nickel, Copper, Iron and Lead. Though there are many more metals than 10.
The softest not exactly the charcoal cat is the softest 2 me ~Puplove56
Bass trees are the softest
The mantle is the softest layer of the Earth.
Lignite is the softest form of coal.
the softest rock is talc and the hardest is a diamond
The two metals with the lowest Mohs hardness scale values are cesium, with hardness 0.2, and rubidium, with hardness 0.3. Lithium, sodium, and potassium metals have values near 0.5-0.6. - - - - - Cesium and rubidium are liquids at or near room temperature--cesium undergoes phase change at 28C, rubidium undergoes phase change at 39C. I knew they were the softest metals on the Mohs scale, but didn't list them because of this low melt point. So...after the liquid metals (there are five--mercury, francium and gallium plus the two already named), you could pick any of the three low-mass alkali metals as the "softest."
Metals are denser than non-metals. They are not necessarily harder though. Hardness has nothing to do with density - it's down to the structure of the bonded molecules. Diamond is one of the hardest know sustances, but it is a non-metal (a form of carbon). Lead and gold are among the softest of metals yet they are also some of the densest.
