Intramolecular Forces vs. Intermolecular Forces Intramolecular forces Intramolecular forces are forces within a molecule and are usually covalent bonds Covalent bonds are formed when the out...
Electronegativity Electronegativity is the power of an atom to attract the pair of electrons in a covalent bond towards itself The electron distribution in a covalent bond between elements w...
Effects of Bonding & Structure on Physical Properties Different types of structure and bonding have different effects on the physical properties of substances such as their melting and b...
Metallic Lattice Structures Metals form giant metallic lattices in which the metal ions are surrounded by a ‘sea’ of delocalised electrons The metal ions are often packed in hexagonal layers...
Covalent Lattice Structures Covalent lattices Covalent bonds are bonds between nonmetals in which electrons are shared between the atoms Covalent compounds can be arranged in simple molecula...
Ionic Lattice Structures Most ionic, metallic and covalent solids are crystalline lattices The ions, atoms or molecules are arranged in a regular and repeating arrangement Giant ionic lattic...
Metallic Bonding: Definition Metal atoms are tightly packed together in lattice structures When the metal atoms are in lattice structures, the electrons in their outer shells are free to mov...
Representing Dot & Cross Diagrams Dot and cross diagrams are diagrams that show the arrangement of the outer-shell electrons in an ionic or covalent compound or element The electrons are...
Dative Covalent Bonding In simple covalent bonds, the two atoms involved share electrons Some molecules have a lone pair of electrons that can be donated to form a bond with an electron-defi...
