What is the clarity of cesium?
Cesium is a highly reactive alkali metal with a silver-white color and a lustrous finish when freshly cut. It is often stored under mineral oil to prevent oxidation from air and moisture.
Is neptunium shiny?
The fresh surface of neptunium is silvery.
Which metals are not lustrous?
Lustre Is An Property Of Metals: Thus All Metals Have Lustre However Lead Being A Metal Is Considered To Be Non Lustrous But Actually Lead Is Bright And Silvery When Freshly Cut But The Surface Rapidly Tarnishes In Air To Produce A Dull Lustre Associated With Lead.
Can potassium be cut with a knife?
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.
Is pure sodium hard?
Pure sodium is a soft and highly reactive metal. It can be easily cut with a knife and has a shiny surface when freshly exposed. However, it is highly reactive with air and water, forming compounds that can quickly tarnish its appearance.
Is beryllium lustrous?
Yes, beryllium is a lustrous metal. It has a shiny surface when freshly cut, but can develop a dull patina over time due to oxidation.

What does Antimony look like?
Antimony is a silvery-white, brittle metal that has a metallic luster when freshly cut. It can appear as a powder, ingots, or as a grayish-black substance, depending on its form and purity.
Explain why the surface of sodium is only shiny when it is freshly cut?
The shiny appearance of freshly cut sodium is due to its high reactivity with oxygen in the air. When sodium is exposed to air, it quickly reacts with oxygen to form sodium oxide, which creates a dull, opaque layer on the surface of the metal. This layer of sodium oxide obscures the shiny surface of the metal, giving it a dull appearance. Therefore, only freshly cut sodium displays its characteristic shiny appearance before it reacts with oxygen in the air.
A typical property of a metal surfaces when freshly cut or polished?

What chemical properties would you expect caesium to have?
Caesium is freshly cut, it have a metallic shine, but this disappears rapidly due to reaction of exposed metal surface with oxygen in the air

Is sodium shiny when it is cut?
yes! very fun BUT DANGEROUS to put in water
What substance is formed when freshly cut lithium metal reacts with air?
lithium oxide
