22 Μαΐ 2021 · Giant ionic lattices. An ionic bond is an electrostatic force between a positively charged metal (cation) ion and a negatively charged non-metal (anion) ion. The metal becomes positively charged as it transfers electrons to the non-metal becomes negatively charged.
Ionic compounds have regular structures (giant ionic lattices) in which there are strong electrostatic forces of attraction in all directions between oppositely charged ions.
Anecdotes for chemistry teachers; Literacy in science teaching; ... Interpret ionic lattice diagrams of an unfamiliar ionic compound. ... This worksheet is ramped so that the earlier questions are more accessible. The activity becomes more challenging in the later questions. You can give extra explanations for the more challenging questions.
The Lattice energy, U, is the amount of energy required to separate a mole of the solid (s) into a gas (g) of its ions. Na + Cl - ( s ) → Na + + ( g ) + Cl - ( g ) U (kJ/mol)
Ionic compounds form extended ionic lattices which contain an ‘infinite’ networks of ionic bonds. Cations lose electrons so that they have an empty outer shell: Group 1 metals lose 1 electron, Group 2 metals lose 2 electrons. and Group 13 metals lose 3 electrons.
Oppositely charged ions attract through electrostatic forces to form a giant ionic lattice. Example: Sodium chloride is an ionic compound formed from Na+ and Cl- ions. Sodium loses an electron and chlorine gains an electron to produce ions with a full outer electron shell. These then attract into an ionic lattice: . Common compound ions include:
Lattice: ordered arrangement / regular arrangement Lattice structure of ionic compounds consists of a regular arrangement of alternating positive and negative ions. (MUST LEARN!) The ions attract each other strongly and are held together in the lattice structure by strong ionic bonds. Cubic lattice structure of Sodium chloride
