Question

which metal is cut by knife

Answer 1

Solution: Lithium, sodium and potassium though highly reactive alkali metal but are soft enough to cut with the knife.

However, no sooner it is cut; the shiny and silvery surface tarnishes while coming into the contact of oxygen and turns dull grey.

This is because a coat of metal oxide is formed on the surface.

Answer 2

Answer:

Sodium and Potassium are the metals that can be cut by knife.

I hope it helps you.
