Which term describes a bond created by positive and negative ions; by a metal and non metal?

• A. Ionic bond
• B. Chemical equation
• C. Hydrogen
• D. Helium

Answer: (A)

A bond formed between positive and negative ions from a metal and a nonmetal is an ionic bond. In this type of bond, the metal tends to lose electrons and become a positively charged ion, while the nonmetal gains those electrons to become a negatively charged ion. The opposite charges attract, pulling the ions together into a compound. This transfer and attraction create a strong bond that often results in a solid with a crystal lattice and high melting points.

A chemical equation is just a way to represent a chemical reaction, not a type of bond. Hydrogen and helium are elements, not bonds, so they don’t describe the linking force between ions.
