Bonds Flashcards
What is an Ionic Bond
Electrostatic forces of attraction between oppositely charged Ions
What is a Covalent Bond
Formed when valence electrons are shared between Non-Metals
What is a Metalic Bond
The electrostatic force between metal ions and the sea of delocalised electrons
Structure of an Ionic Bond
Lattice
Structure of a Covalent Bond
Molecular
Structure of a Metalic Bond
Lattice
Explain why Ionic bonds have a High Melting Point
More heat is needed to separate the electrostatic forces of attraction between the ions
Explain why Covalent Bonds have a Low Melting Point
Less heat is needed to separate the weak Van Der Waals force between the molecules
Define Van Der Waals Force
Forces of attraction between Valence shells
Explain why Metalic Bonds have a High Melting Point
A lot of heat is required to overcome the strong electrostatic forces of attraction between the electrons and ions due to the large sea of delocalised ions
Rank the Melting points of the Ionic bond, Covalent bond and Metalic bond from Low to High
Covalent Bond - Ionic Bond - Metalic Bond
Out of the 3 Bonds which can conduct electricity and why
Ionic, but only in its molten state as there are free moving Ions and Metalic as there are free moving ions from the sea of delocalised ions
