Answer:
The correct answer is Ionic Bond
Step-by-step explanation:
Group 2 elements are majorly metals, which include Magnesium (12), calcium (20), and some other metals, while the nonmetal from group 6 includes Oxygen (8), sulfur (16). The nonmetal gain electrons from the metal.
When metals in group two combine with nonmetal in group 6 they form an Ionic bond which is a strong bond.
The remaining electrons in the outer shell are transferred when the oppositely charged ions of both elements combined. Where the metal transfers electrons to the nonmetal. For example, Magnesium (Mg) + Oxygen (O) = MgO. Magnesium transfers its (2) outer electrons to oxygen.
