Applied Science AQA/Bonding and Structure

Topic Title Edit

Setting Applied context Edit

Materials scientists are involved in the applications of existing materials to new contexts, and the developments of new materials such as graphene-based nanomaterials. They need a knowledge and an understanding of the structures of those materials and the type and strength of forces present. 

Syllabus Content What you need to do
•    formulas for common cations

•    formulas for common anions (sulfate, carbonate, nitrate, hydroxide)

•    deducing formulas for ionic compounds

•    ionic bonding and ionic crystal lattices in terms of strong electrostatic forces of attraction

•    a covalent bond as a shared pair of electrons

•    multiple bonds, neutral molecules, non-conductors and weak intermolecular forces of attraction

•    metallic bonding

•    structures of:

•    ionic crystal lattices typified by sodium chloride, magnesium oxide

•    metallic lattices typified by magnesium

•    covalent structures typified by iodine, methane, carbon dioxide

•    giant covalent structures (macromolecular), eg diamond, graphite, graphene, fullerene

•    predicting types of bonding for compounds given their typical properties and vice versa • typical properties based on the type of bonding, particles present and forces between particles

•    common physical properties of materials related to their structure and bonding, to include:

•    electrical conductivity

•    melting point and boiling point

•    volatility

•    solubility in water

•    non-polar solvents

•    drawing diagrams to represent: • a named ionic lattice

•    a generalised metallic lattice

•    an alloy

•    giant covalent structures, including silicon, graphite, graphene.

Exploration of key ideas (must be original text, not C&P) – level checked by AQA Edit

In general, point students towards the approach to take, as opposed to just giving them information.

Careers and Organisations Edit

Carry out some research into these jobs in this area. (Feel free to add other jobs you find.)

Research these roles: What are the benefits of this role to society? What organisations would employ someone in this role? 

(Where would they work?)

What would someone in this role have to do within the organisation? What scientifically-related skills do they need to have? 

What techniques do they need to have mastered?

What experience is needed to undertake this role and its responsibilities within an organisation? What other science personnel will they work with in their organisation.
