Answer

Answer:

B. group 17

Explanation:

Step1: Understand ionic - bond formation

Ionic bonds form between a metal and a non - metal.

Step2: Analyze group 2 metals

Group 2 metals are alkaline earth metals and are metals. They tend to lose 2 electrons to form cations.

Step3: Analyze each group

  • Group 1 are alkali metals, also metals, so they don't form ionic bonds with group 2 metals.
  • Group 17 are halogens, non - metals. They gain 1 electron to form anions. Group 2 metals can form ionic bonds with group 17 elements. For example, calcium (Ca, group 2) can form calcium chloride ($CaCl_2$) with chlorine (Cl, group 17).
  • Group 18 are noble gases, which are very stable and do not readily form chemical bonds.
