Question

How to know if two elements will form an ionic compound?

Answer 1

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:

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.

Answer 2

Two elements will form an ionic compound if one element is metal and another element is non-metal.

Explanation:

• If one element is metal and another element is non-metal, then the bond formed between them will be an ionic compound.
• The element which is metal is able to lose electrons while the non-metal is capable of accepting electrons.
• Thus, the transfer of electrons will occur from one element to another element which leads to the formation of an ionic compound.
• In such a case, the metal will form a cation by losing electrons while the non-metal will form an anion by accepting electrons.
• Thus, an ionic bond will be formed in such a case.
