The metal activity series is an arrangement of metals in the decreasing order of reactivity. The most active metals are placed at the top of the series while the least reactive metals are placed at the bottom.

$\begin{tabular}{|c|c|}\cline{1-2}\ \bigstar\:{\bf{ Element}\:\bigstar}& \bigstar\:{\bf{Symbol}\:\bigstar} \\ \cline{1-2}\ Potassium & K \\\cline{1-2}\ Sodium & Na \\ \cline{1-2}\ Calcium & Ca \\ \cline{1-2}\ Magnesium & Mg \\ \cline{1-2}\ Aluminium & Al \\ \cline{1-2}\ Carbon & C \\ \cline{1-2}\ Zinc & Zn \\ \cline{1-2}\ Iron & Fe \\ \cline{1-2}\ Tin & Sn \\ \cline{1-2}\ Lead & Pb \\ \cline{1-2}\ Hydrogen & H \\ \cline{1-2}\ Copper & Cu \\ \cline{1-2}\ Silver & Ag \\ \cline{1-2}\ Gold & Au \\ \cline{1-2}\ Platinum & Pt \\\cline{1-2}\end{tabular}$

Potassium is the most reactive and Platinum is the least reactive metal.

The highly reactive metals such as Potassium and Sodium react explosively with oxygen,water, acids and bases.

Metals such as silver, gold and platinum have none or little reaction with most chemicals, hence they are known as Noble metals.
