Explanation:

• Metals are elements that tend to lose electrons. Strontium (Sr) is in Group 2 of the periodic table. Group 2 elements are metals.
• When a metal forms an ion, it loses electrons. Since Sr is in Group 2, it loses 2 electrons. A positively - charged ion (cation) is formed when an atom loses electrons.

Answer:

• Is this element a metal or nonmetal? Metal
• Is the formed ion a cation or an anion? Cation
