Answer: According to the reactivity of metals Sodium is the second metal while Magneesium is the fourth metal. The metal in the top of the reactivity serise table are more reactive.

(The series obtained by the arrangement of metals in the decending oder of their  reactivity is the REACTIVITY SERIES TABLE)

Explanation:

K

Na

Ca

Mg

Al

Zn

Fe

Sn

Pb

H

Cu

Hg

Ag

Pt

Au

Therefore Sodium is more reactive than Magnesium

Answer:

The alkaline-earth metals tend to lose two electrons to form M 2+ ions (Be2+, Mg2+, Ca2+, and so on). These metals are less reactive than the neighboring alkali metal. Magnesium is less active than sodium; calcium is less active than potassium; and so on. These metals become more active as we go down the column.
