Answer 2

Answer:

•Diamond (Carbon) is a non-metal which is the hardest naturally occurring substance.

•mercury (Hg)

The only stable liquid elemental metal at room temperature is mercury (Hg), which is molten above −38.8 °C (234.3 K, −37.9 °F).

•Sodium and Potassium metals are the two metals which are soft and can be cut with a knife.

•Steel is an alloy of iron and carbon, but the term alloy steel usually only refers to steels that contain other elements— like vanadium, molybdenum, or cobalt—in amounts sufficient to alter the properties of the base steel.

•Hence, Non - metal which is stored in water is Phosphorous.
