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.

What metals do not have the usual metallic properrties?
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.
Is potassium softer than sodium?
Chemical formula of potassium bromide is KBr. Potassium and bromide ions make a giant lattice. It is very hard.
What happens when you cut sodium or potassium?
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.
Which metals can be cut with a knife?
Lithium can be cut with a knife because the elements built in it are very sof tand timid.
When Liquid helium is cut off by a power loss what happens to a MRI magnet?
After liquid helium is cut off, the temperature could rise up and reach temperature. Under these circumstances, the magnet can demagnetise

Can potassium be cut with a knife?
YES
Can you liquefy salt?
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.
Which 2 metals that can be cut with a knife?
sodium and potassium are the two metals that can be cut by a knife.
What are facts about the element potassium?
o Pure potassium is a lightweight silvery metal that is soft enough to cut with a knife.
Is potassium shiny on the periodic table?
Potassium is an alkali metal.It is shiny when freshly cut but quickly go dull.
What does freshly cut potassium look like?
It is shiny but starts to turn darker straight after being cut.
Which element is a solid at room temperature can be cut easily with a knife and can conduct electricity A.sodium B.argon C.mercury D.Iron?
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.
Is Lithium at room temperature solid liquid or gas?
Lithium is a metal. It is soft and is a nice shiny silvery colour when first cut. It is very reactive.
What state does potassium normally come in?
At standard temperature and pressure Potassium is a solid metal which is soft enough to be cut with a sharp knife.
Is an element that is soft and easy to cut cleanly with a knife likely to be a metal or a non metal?
The Alkali Metals. Lithium, Sodium, Potassium, Rubidium, Cesium, and Francium.
Is potassium softer than sodium?
Chemical formula of potassium bromide is KBr. Potassium and bromide ions make a giant lattice. It is very hard.
