Q2. Why is calcium a poor choice for a metal to be used in pipes used for plumbing?
Q3. Which metal should be more reactive - francium or potassium? Why? (Consider the electron configuration of each atom).
Q4. Consider the placement of Na, K, Ca, Cu, Mg and Z on the periodic table. Does their placement reflect their physical properties? How?
Provide complete and step by step solution for the question and show calculations and use formulas.
