componetn 1 short review Q3 how would you describe a chemical bond?
Answer (1)
A chemical bond is the force of attraction that holds two or more atoms together in a compound. It happens when atoms either share or transfer electrons in order to become stable. Atoms want to achieve a full outer shell of electrons, and they bond with other atoms to do that.Main Types of Chemical BondsIonic Bond – One atom donates electrons to another. This usually occurs between a metal and a nonmetal. Example: Sodium (Na) gives an electron to Chlorine (Cl), forming NaCl (salt).Covalent Bond – Atoms share electrons to complete their outer shells. Usually happens between nonmetals. Example: Water (H₂O) is formed when two hydrogen atoms share electrons with an oxygen atom.Metallic Bond – Occurs between metal atoms. Electrons move freely, which allows metals to conduct electricity and be malleable. Example: Iron or copper.Chemical bonds are responsible for the structure of everything around us—from the air we breathe to the food we eat. They determine the physical and chemical properties of substances, like boiling point, strength, and how substances react with each other.Understanding chemical bonds is essential in science because it explains how molecules are built and how chemical reactions happen in nature and in the body.
