Metals that can be cut easily are the alkali metals. They are "soft" metals that can be cut with a knife.
Most of the Alkali metals are soft enough to be cut with a knife, certainly Sodium, Potassium and Rubidium are.
Lithium and possibly sodium
Rubidium is a metal, but it isn't considered to be malleable for two main reasons: first, it is not very hard; in fact you can cut it easily with a knife; second, it is so highly reactive that it would not be practical to try to shape it. Being an alkali metal in period 5, it is explosively reactive even with air.
When a more reactive metal sacrifices itself for a less reactive metal to prevent the lesser reactive metal from rusting. :-)
caesium is the most reactive non-radioactive metal and Florine is the most reactive non-metal, but francium is the most reactive, radioactive metal
Sodium is indeed very reactive with water because it is an Alkali metal. These metals have low melting points. Like the sodium, they are soft enough to be cut with a knife. They are highly reactive.
elements that is soft and easy to cut cleanly with a knife likely to be metal or a nonmetal
Na (Sodium) is an alkali metal that can be cut with a knife.
Metal.
The lettuce does not turn brown due to it being cut with a metal knife. It turns brown due to oxidation.

Lithium and possibly sodium
Yes, it causes a small explosion when placed in water and it can also be cut with a knife
No. At standard temperature, sodium is a highly reactive, silvery-gray metal that is soft enough to be cut with a knife. At standard temperature, chlorine is a dangerous and poisonous yellowish-green gas which exists as Cl2.
