State the electron rules : Lowest energy filled first (3d>4s) Line up parallel Single until forced to pair Electronegativity : The ability of an atom to attract electrons within a covalent bond RAM (relative atomic mass) : Average mass of one atom compared to 1/12th the mass of a c-12 atom - Ionisation energy : The energy required to remove one mole of electrons from each of one mole of gaseous atoms to form one mole of positive gaseous ions 2 (Endothermic) Trends of Ionisat...

AQA A level Chemistry Mass Spectrometry Questions and Answers Already Passed Q: What do you need to remember about these cards? - Make sure you have the Q side visible first ( quizlet only let me upload images in the answers) - most A-level marks are for application so you need to memorise these facts so we can spend lesson time on application. Q: What is mass spectrometry? it is a powerful instrumental method of analysis. It can be used to: - find the abundance and mass of each isotope in an ...

This question is about atomic structure.There is a general trend for an increase in ionisation energy across Period 3. Give one example of an element that deviates from this trend. Explain why this deviation occurs. : Aluminium / Al(Outer) electron in (3)p orbital / sub-shell (level) (3p) higher in energy / slightly more shielded (than 3s) / slightly further away (than 3s) Give an equation, including state symbols, to represent the process that occurs when the third ionisation energy of...
