The reaction is exothermic. During the reaction, the sodium metal may well become so hot that it ches fire and burns with a characteristic orange colour. The reaction is slower than that of potassium (immediately below sodium in the periodic table), but faster than that of lithium (immediately above sodium in the periodic table).

there will be no reaction - nothing will happen! For example, iron is less reactive than magnesium. iron + magnesium sulfate no reaction. In these displacement reactions the metals are competing for the non-metal anion. In the above examples the non-metal anion
Alkali metal - Chemical properties | Britannica
5/8/2020· Alkali metal - Alkali metal - Chemical properties: Since the alkali metals are the most electropositive (the least electronegative) of elements, they react with a great variety of nonmetals. In its chemical reactivity, lithium more closely reseles Group 2 (IIa) of the periodic table than it does the other metals of its own group. It is less reactive than the other alkali metals with water

Paramagnetism of Transition Metal Salts | Chemdemos
Paramagnetism is when a substance is weakly attracted to a magnetic field. It occurs when there are unpaired electrons in the substance. Paramagnetism is most easily observed in the salts of some of the first row transition metals (manganese through nickel). The se metal ions have unpaired electrons in degenerate d orbitals as predicted by Hund''s rule and thus exhibit paramagnetism.
