Ionic bonding
The electrostatic attraction between oppositely charged ions.
giant covalent lattice
A three-dimensional structure of atoms, bonded together by strong covalent bonds.
giant ionic lattice
A three-dimensional structure of oppositely charged ion, bonded together by strong ionic bonds.
giant metallic lattice
A three-dimensional strucutre of positive ions and delocalised , bonded together by strong metallic bonds.
covalent bond
The electrostatic attration between a shared pair of electrons.
lone pair
A pair of electrons in the outer shell not used in bonding.
Dative covalent bond
A shared apir of electrons which has been provided by one of the bonding atoms only, also called a coordinate bond.
simple molecular structure
A simple molecular lattice is a three dimensional structure of molecules,bonded together by weak intermolecular forces.
Giant covalent lattice
Atoms joined together covalently in a regular repeating structure with no absolute size.
Giant structure
A repeating lattice with no fixed number of particles.q
metallic bond
Electrostatic attraction between cations and a “sea” of delocalised electrons.
malleable
Can be beaten into sheets
Ductile
Can be drawn into a wire.
Valence Sheel Electron Pair Repulsion Theory states:
Electron pairs repel each other.
The repulsion between a lone pair and another lone pair is greater than the repulsion between a lone pair and a bonded pair which greater than the repulsion between two bonded pairs.
