Chemical Bonds: Covalent, Ionic, and Metallic
Explore the fascinating world of chemical bonds, including covalent bonds where atoms share electron pairs (e.g., water), ionic bonds where oppositely charged ions attract (e.g., sodium chloride), and metallic bonds formed between positively charged atoms sharing free electrons (e.g., copper wire). Learn about the forces holding atoms together and the types of bonds that exist in various substances.

Chemical Bonds A force of attraction that holds two atoms together
Types of Chemical Bonds Covalent Ionic Metallic
Covalent Bonds A type of bond where atoms share electron pairs Example: Water H2O. Hydrogen and oxygen atoms share electrons.
Ionic Bond In ionic bonding opposites attract. The bond occurs when positively charged and negatively charged ions interact. In this example, one atom may lose an electron while the atom it bonds with gains an electron. Example: Sodium Chloride
Metallic Bond A type of chemical bond formed between positively charged atoms in which the free electrons are shared Example: Copper wire
