O. Sproston Structure and bonding Flashcards
The definition of an ionic bond
The strong electrostatic attraction between oppositely charged ions
Definition of Covalent Bond
The strong electrostatic attraction between the nuclei and the shared electron pairs
Metallic compounds definition
The strong electrostatic attraction between the metallic cations and the delocalised sea of electrons
Simple molecular substances with covalent bonds have a low melting point beacause…
IMFs are weak between individual molecules
What structure do ionic compounds form
Giant Ionic Lattices
Metallic compounds conduct electricity. Why?
The electrons are delocalised and free to move which means that charge can flow through the metal
Diamond is the strongest substance which can theoretically be found. Why?
Diamond forms a giant covenant compound, and since it is formed with Carbon, it is a covalent bond which is the strongest bond formable. Carbon also forms bonds with 4 other carbon atoms in the tetrahedral structure
IMF stands for…
Inter-molecular forces.
