Potassium metal at room temperature is a soft silvery colour, and oxidizes rapidly in contact with the air. It is usually kept in a glass jar, under a hydrocarbon liquid such as kerosene. It is about the texture of stiff modelling clay.
When in contact with water it reacts with vigour, and will ignite the hydrogen released in the reaction with water.
It is a solid, only in extreme heat it would be a liquid. And Im not sure what would make it a gas.
Sodium and potassium can be cut very easily with a normal kitchen knife so it does not show normal metallic characteristics which tells that a metal is hard . Lead another metal has very low melting point, which is opposite to the statement that metals have high boiling and melting point. Mercury and gallium are in liquid phase at room temperature which opposes that metals are solid at room temperature. These metals are called exceptions.
Lanthanum is a solid at room temperature. It is a soft, malleable metal that can be easily cut with a knife.
Chemical formula of potassium bromide is KBr. Potassium and bromide ions make a giant lattice. It is very hard.
When you cut the likes of sodium or potassium it leaves a shiny surface which will quickly turn dull as they react with Oxygen in the air. To prevent them reacting with any of the air, these elements are usually kept in oil.

Potassium is a soft, silvery metal that is easily cut with a knife. In its normal state, it is a solid at room temperature and has a shiny appearance. It is highly reactive with water and oxygen, quickly forming oxides.
Yes, potassium is a soft metal and can be easily cut with a knife. However, caution must be taken as the freshly cut surface of potassium reacts vigorously with oxygen and moisture in the air, leading to fire or explosion.
Yes potassium liquifies salt. Take an avocado for instance very high potassium levels. (Much more than a bannana) and sprinkle some salt on some cut Leicester and wait. You will see it turn into liquid droplets.
Potassium typically has a metallic lustre, appearing shiny and reflective when freshly cut.
Lanthanum is a solid at room temperature. It is a soft, malleable metal that can be easily cut with a knife.
sodium and potassium are the two metals that can be cut by a knife.
Potassium is an alkali metal.It is shiny when freshly cut but quickly go dull.
Sodium is a soft solid at room temperature, so it can be cut. It is a metal, so it conducts electricity.Argon is not a metal, and is a gas at room temperature. Mercury is a metal, but is a liquid at room temperature. Iron is a metal, and is solid at room temperature, but is too hard to cut with a knife.
It is shiny but starts to turn darker straight after being cut.
The Alkali Metals. Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
