AS Level Chemistry

AS Level Chemistry Atomic number - answer-Number of protons in an element Mass number - answer-Number of protons and neutrons Ion - answer-Electrically charged particle formed by the loss/gain of electrons Relative masses of P,N and E - answer-1,1, 1/2000 (respectively) Isotopes - answer-Atoms of the same element with different number of neutrons but same number of protons. What are steps of mass spectroscopy? - answer-Ionisation, Acceleration, Deflection, Detecting Ionisation - answer-A gaseous sample is bombarded with high energy electrons to create 1+ ions Acceleration - answer-They are accelerated through magnetic/electric field Deflection - answer-Ions are deflected through magnetic field according to mass (heavy - deflect least)(light - deflect most) Detection - answer-A calibrated detector records degree of deflection and interprets this into mass What does mass spectroscopy provide? - answer-Information about masses of particles inside machine and how often it's detected...
