Study Notes
Types of Bonding in Elements and Compounds
- There are three main types of bonding in elements and compounds: covalent, ionic, and metallic.
- Covalent bonding occurs when non-metal atoms share electrons, forming a strong covalent bond.
- Simple covalent compounds are small molecules like CH4, H2O, and CO2, while giant covalent compounds include diamond, graphite, graphene, and silicon dioxide.
- Ionic bonding occurs when metals and non-metals react together, forming a giant ionic lattice of positive and negative ions held together by a strong electrostatic attraction.
- Examples of ionic compounds include calcium chloride, magnesium oxide, and aluminum bromide.
- Metallic bonding occurs only within metals, where positive ions and delocalized electrons form a giant metallic lattice held together by a strong electrostatic attraction.
- Examples of metallic substances include magnesium, calcium, aluminum, copper, sodium, and iron.
- Covalent bonding can only occur between non-metal elements.
- Ionic bonding requires at least one metal and one non-metal element.
- Metallic bonding only happens within metals and never between non-metals.
- A covalent bond is a shared pair of electrons between two atoms.
- An ionic bond is a strong electrostatic attraction between positive and negative ions, while a metallic bond is a strong electrostatic attraction between positive ions and delocalized electrons.
