▶Sodium is a highly reactive metal which lies in group 1 and period 1 of modern periodic table.So, we can convey that its valency is +1 which means it need to lose one electron to be stable like nearest noble gas neon.
▶Chloride is a non metallic negative radical with valency -1 .
◼So,when sodium reacts with chloride it loses its one electron to chloride and forms sodium chloride.
▶Sodium is a highly reactive metal which lies in group 1 and period 1 of modern periodic table.So, we can convey that its valency is +1 which means it need to lose one electron to be stable like nearest noble gas neon.
▶Nitrate is the negative radical with valency -2 .So it needs 2 electrons to be stable like nearest noble gas.
◼So, two atoms of sodium reacts with nitrate radical to form sodium nitrate.
They both can be distinguish by heating.
✳When sodium chloride is heated it does an highly exothermic reaction and after completion of reaction the salt turns yellowish because of chlorine atom.
✳When sodium nitrate is heated it gives out a reddish brown gas which is nitrogen dioxide and leaves a metallic oxide that is sodium oxide.
