Question

Explain, Some alkali metals can be cut with a knife.

Answer 1

Due to the presence of weak metallic bonding alkali metals are soft and can be cut with a knife. ii) Reactivity of metals depends on ionization energy or ionization enthalpy. Ionization enthalpy of an element depends on its atomic radius. ... Therefore, potassium is more reactive than sodium.

Answer 2

Some alkali metals can be cutwith knife because they are very soft and have low densities
