Bonding Flashcards
(12 cards)
Define Ionic Bonding
Occurs between a metal and a non metal, electrons are transferred from one atom to another, strong attraction between oppositely charged ions
Define covalent bonding
Two atoms have a shared pair of electrons which causes a bond
Define Dative / Co-ordinate Bonding
A lone pair of electrons are donated from one atom to another forming a bond
Define Metallic Bonding
A lattice of positively charged ions surrounded by a sea of delocalised electrons
Define a Simple Molecular Structure
A substance that consists of only covalent bonds and it heals together by weak van der waals forces
Define a Macromolecular Structure
A giant lattice of covalent bonds, where each atom has multiple covalent bonds.
Define Electronegativity
An atoms ability to attract a pair of electrons within a covalent bond
Give the three types of Inter Molecular Forces in order of strength
- Van der waals
- Permanent dipole dipole
- Hydrogen bonding
