Question

sodiu is a very reactive metal but it is used as salt in homes​

Answer 1

As a part of the alkali metal group in the periodic table, sodium is highly reactive and is never found pure in nature. It tarnishes easily and has a low melting point and density. ... Within the alkali metals, sodium is more reactive than lithium but less reactive than potassium

Answer 2

Answer:

It helps us understand why the elements in the first row (alkali metals) have large atoms that lose valence electrons so easily and are therefore so reactive. Sodium atoms have a high shielding effect and low effective nuclear charge causing them to have a weak hold on their valence electron.
