G28 have a checkpoint assessment in Science next week on Tuesday . Students have been directed to help via their Google classrooms.
Students should focus upon the following targets:
LT1 I can use the periodic table to work out what different elements need to be stable
- I can interpret the Mass and atomic number in terms of the structure of an atom
- I can draw the electronic configuration of the first 20 elements
- I can describe how ions are formed and what charge they will have
- I can write accurate chemical formula of compounds based upon their position in the periodic table
LT2 I can explain the properties of ionic compounds using knowledge about ionic bonds
- I can explain the electrostatic forms holding ions together in an ionic bond
- I can represent ions using dot and cross diagrams
- I can explain the formation of an ionic lattice structure
- I can I can explain the melting and boiling points, solubility and the conductivity of ionic compounds
- I can write accurate chemical formula of compounds based upon their position in the periodic table
LT3 I can explain the properties of covalently bonded compounds and elements
- I can explain how a covalent bond is formed
- I can represent simple covalent molecules using various methods
- I can explain the melting and boiling point, and conductivity of small covalent molecules
- I can describe the structure of giant covalent materials and explain their properties (Diamond, Graphite, Fullerenes, and silicon dioxide.)
- I can describe the size of nanoparticles
- I can explain the properties and uses of nanoparticles.
