Answer: A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
A pair of elements will most likely form an ionic bond if one is a metal and one is a nonmetal. These types of ionic compounds are composed of monatomic cations and anions.
Explanation:
The chart below shows monatomic ions formed when an atom loses or gains one or more electrons, and the ionic compounds they form. You can check your periodic table to see that the cations are monatomic ions formed from metals, and the anions are monatomic ions formed from nonmetals.
 
        
             
        
        
        
Explanation:
Two events involving electrons are gain and loss of electrons. 
When there is gain or loss of electrons between two atoms then it results in the formation of ionic bond. 
Whereas when there is sharing of electrons between two atoms then it results in the formation of covalent bond. 
Therefore, the chemical bonds formed can be ionic or covalent bonds.
