Answer 1

sodium is highest reactive then calcium then magnesium and then aluminium in the above mentioned metals.

sodium>calcium>Magnesium>Aluminium

hope it will help......

Answer 2

rectivity serioes of metal
k=potasium[most reactive]
Na=sodium
Ba=barium
Ca=calcium
Mg=magnesium
Al=aluminium
Zn=zinc
Cr=chromium
Fe=iron
Cd=cadium
Co=colbat
Ni=nickel
Sn=tin
Pb=lead
(H)=hydrogen
Cu=copper
Hg=mercury
Ag=silver
Au=gold
Pt=platinum [least reactive]
#the at the bottom of the reactive series are least reactive and often found in free state in nature .
