Chemical Bonds
Cards (4)
- Atoms can chemically bond (join together) in 3 ways: ionic bonding, covalent bonding or metallic bonding.
- Ionic bonding
- Ionic bonding involves an attraction between oppositely charged ions.
- Ionic bonds are found in compounds made of metals and non-metals.
- Covalent bonding
- Covalent bonding involves 2 atoms sharing 1 or more pairs of electrons.
- Covalent bonds are found in most non-metal elements and in compounds of non-metals.
- Metallic bonding
- Metallic bonding involves an attraction between positively charged ions and negatively charged, delocalised electrons.
- Metallic bonds are found in metals and alloys (mixtures of metals and other substances).
