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.
Properties of ionic substances – building ionic lattices. GCSE worksheet on explaining properties of ionic substances. Students build a model of an ionic lattice using plasticine and straws. They then use this model to explain a variety of physical properties of sodium chloride including high melting point, conductivity and brittleness.
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.
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)
20 Μαρ 2021 · Giant ionic structures is the fifth lesson in the AQA GCSE Chemistry ‘Structure, bonding, and the properties of matter’ topic in paper 1. The main things I want students to take away from this resource is the ability to explain the properties of ionic substances.
Ionic compounds form in strict ratios of anions to cations to gain overall neutrality. For example, Ca2+ and Cl-will form an ionic lattice in the ratio 1 : 2 (1 × 2 + 2 × (-1) = 0). The resulting ionic compound has the formula CaCl2 and is calcium chloride. Notice that the cation is given first in the formula and name. 4.
ionic lattice. The regular arrangement of ions in an ionic substance. The lattice is formed because the ions attract each other and form a regular pattern with oppositely charged ions...
