Answer 2

Sodium and Potassium metals are the two metals which are soft and can be cut with a knife.

Reason:

-->Sodium and Potassium belongs to Alkali metals [first group of periodic table]

-->They are reactive metals.

-->As the atomic size increases down the group, hence the force of attraction between the valence electron and nucleus decreases. 

-->Metallic bonds are not strong .

-->Hence they are soft.
