What kind of chemical bond is formed between nonmetals? Explain your answer.

Answers

Answer:

The ionic bond is formed due to an electrostatic force of attraction between two oppositely charged ions. This bond is usually formed between a metal and a nonmetal. Prior to the electrostatic attraction, there is a total transfer of valence electrons from one atom to the other atom.

Explanation: hope that helps

In general, nonmetals form covalent bonds, metals and nonmetals form ionic bonds, and metals form metallic bonds.

What are non-metals?

Non-metals are natural materials that do not generate heat or electricity and are structurally brittle, making them difficult to roll, mold, extrude, or press.

Non-metallic elements in the periodic table include hydrogen, carbon, nitrogen, oxygen, phosphorus, arsenic, and selenium.

Ionic compounds are formed when metals and nonmetals combine, whereas covalent compounds are formed when nonmetals combine with other nonmetals.

Metal atoms have only a few electrons in their outer shell, whereas non-metal atoms have many electrons.

This means that metals are more likely to react with nonmetals. Electrons transfer from the metal to the nonmetal when it reacts with it.

Thus, there will be covalent bonding between nonmetals.
