Bonding Questions: E.g. melting point question ‘in terms of bonding and structure.’ - Name structure. - Name bond. - Write what the attraction is between e.g. + metal ions and –ve delocalised electrons in metallic, atoms in covalent bond and molecules in simple...
Covalent Bonding: It is the strong electrostatic force of attraction between a shared pair of electrons and the nuclei of the bonded atoms. Covalent bonding occurs between non- metallic elements and polyatomic ions. • Orbital Overlap: A covalent bond is the overlap of...
Shells are energy levels. • Atomic Orbitals: It is region around a nucleus that can hold up to two electrons, with opposite spin. Must have opposite spin due to repulsion between two negative electrons. • Four Different Atomic Orbitals: s-, p-, d- and f-. The greater...
