An ionic compound is formed if the electronegativity difference between the two atoms is above 1.7 and this is generally true in the case of metals and non-metals.

Why are ionic compounds formed when a metal from the left side of the periodic table reacts with a nonmetal from the left side?

When a metal from the left side of the periodic table reacts with a nonmetal from the right side, electrons are transferred from the metal to the nonmetal. The metal loses electrons to form a positively charged cation, while the nonmetal gains electrons to form a negatively charged anion. These oppositely charged ions then attract each other to form an ionic compound.


When a metal reacts with a nonmetal a colvent bond is formed true or false?

False. When a metal reacts with a nonmetal, an ionic bond is typically formed, rather than a covalent bond. In an ionic bond, electrons are transferred from the metal to the nonmetal, resulting in the formation of ions with opposite charges that are held together by electrostatic forces.


An ionic compound is formed when there is a reaction between what elements?

Ionic compounds are formed when a metal reacts with a nonmetal. The metal atom loses electrons to become a positively charged cation, and the nonmetal gains these electrons to become a negatively charged anion. These opposite charges attract each other, forming an ionic bond.


What are ten examples of reactions between metal and nonmetal?

Sodium (metal) reacts with chlorine (nonmetal) to form sodium chloride. Magnesium (metal) reacts with oxygen (nonmetal) to form magnesium oxide. Aluminum (metal) reacts with sulfur (nonmetal) to form aluminum sulfide. Lithium (metal) reacts with nitrogen (nonmetal) to form lithium nitride. Potassium (metal) reacts with fluorine (nonmetal) to form potassium fluoride. Calcium (metal) reacts with phosphorus (nonmetal) to form calcium phosphide. Barium (metal) reacts with iodine (nonmetal) to form barium iodide. Titanium (metal) reacts with carbon (nonmetal) to form titanium carbide. Iron (metal) reacts with chlorine (nonmetal) to form iron(III) chloride. Zinc (metal) reacts with sulfur (nonmetal) to form zinc sulfide.


When a metal reacts with a nonmetal are the substances good conductors of electric current?

It depends on the nature of the metal-nonmetal compound formed. Metal-nonmetal compounds, known as ionic compounds, are usually poor conductors of electric current in solid state due to the lack of free-moving electrons. However, when dissolved in water or melted, they can conduct electricity due to the presence of mobile ions.
