Applied Science AQA/Atomic Structure

Reference material by Wikibooks contributors. This retains its source identity and is not 411 news reporting.

Topic Title Setting Applied context Scientists working in any area of chemical industry or research require a firm understanding of atomic structure and electron configurations and their use in providing the fundamental basis for chemical structures and reactions. Radiographers, environmental chemists and archaeologists all make use of specific isotopes in their work. Analytical chemists use UV/visible spectra and flame emission spectra to help characterise substances and colorimetry as a quantitative analytical technique. The origin of colour in compounds is of great importance in the dye-, pigment-, and paint-based industries and to development chemists researching new products. Syllabus ContentWhat you need to do•    atomic structure in terms of protons, neutrons and electrons, and their relative charges and relative masses •    the terms atomic (proton) number (Z), mass number (A), isotope, isotopic abundance •    electron configurations for atoms and ions up to Z = 36 in terms of shells•    the origin of coloured flame emission spectra and of colour in transition metal compounds in terms of electron transitionscalculating relative atomic mass, relative molecular mass and relative formula mass in terms of 12 C. Exploration of key ideas (must be original text, not C&P) – level checked by AQA In general, point students towards the approach to take, as opposed to just giving them information.

(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.Job 1Job 2 Relevant practical/s – relating to criteria skills Quick questions quick questions Solution click to reveal answer hidden Exam-style questions – can we use old AQA qs… e.g. from more than 5 years ago?
