Answer

Answer:

A. potassium (K)

Explanation:

Step1: Recall periodic - table trends

Reactivity of metals increases down a group and decreases across a period.

Step2: Locate elements

Rubidium (Rb) is in Group 1, Period 5. Calcium (Ca) is in Group 2, Period 4.

Step3: Analyze options

  • Potassium (K) is in Group 1, Period 4. It is less reactive than Rb (below it in Group 1) and more reactive than Ca (to the left of Ca in Period 4).
  • Cesium (Cs) is in Group 1, Period 6, more reactive than Rb.
  • Magnesium (Mg) is in Group 2, Period 3, less reactive than Ca.
  • Titanium (Ti) is a transition metal, less reactive than Group - 1 and Group - 2 metals.
