Arrange the following metal in the increasing order of their reactivity towards water: Zinc, Iron, Magnesium, Sodium.

Q. Which sequence indicates correctly the increasing reactivity of metals?
(a) iron, zinc, magnesium, sodium, potassium
(b) sodium, potassium, magnesium, zinc, iron
(c) magnesium, potassium, sodium, iron, zinc
(d) iron, zinc, sodium, magnesium, potassium

Q. Arrange the metals: calcium, iron, magnesium and sodium in order of their activity with water placing the most reactive first.

Q. Statement I: Zinc can displace iron but not magnesium from their salt solutions.
Statement II: Magnesium can displace both iron and zinc from their salt solutions.

Based on the above statements, arrange the following elements in decreasing order of their reactivity.

(v) Most reactive metal is sodium.

(vi) Gold is least reactive.

(vii) Calcium and zinc metals displace iron.
