Final answer:
Atoms from group IIA and group VIIA typically form ionic compounds, resulting from the formation of an ionic bond between the positively charged metal cations and negatively charged nonmetal anions. correct answer is option a.
Step-by-step explanation:
When atoms from an element in group IIA (which are metals) react with atoms from an element in group VIIA (which are nonmetals), the ionic compounds are typically formed. This occurs as the atoms from group IIA tend to lose electrons and form positively charged ions, or cations, while the atoms from group VIIA tend to gain these electrons, thus forming negatively charged ions, or anions. The result is the formation of an ionic bond between these oppositely charged ions.
Atoms from group IIA and group VIIA typically form ionic compounds, resulting from the formation of an ionic bond between the positively charged metal cations and negatively charged nonmetal anions.
