Q:

When Ionic bonds are formed metallic atoms tend to

A) share electrons B) gain electrons
C) lose electrons D) None of above
 
Answer & Explanation Answer: C) lose electrons

Explanation:

Ionic bonding is the complete transfer of valence electron(s) between atoms. It is a type of chemical bond that generates two oppositely charged ions. In ionic bonds, the metal loses electrons to become a positively charged cation, whereas the nonmetal accepts those electrons to become a negatively charged anion.

 

Hence, when Ionic bonds are formed metallic atoms tend to lose electrons and become positive ions
