i see, so do you go on the student room.

whats philosophy like (btw do you go on the student room)

finsished all my exams in the first week bio,chem,physics - what subjects do you take ?

what are u AS or A2 level

yh it is l0l . The questions seemed a bit d0dgey th0 (i think they were trying to confuse people with the wording of the questions), how did you find the rest of the exam.

Hi: a) an atoms electron is in the ground state (-4.11*10^ -17). An electron with ke 5*10^-17 collides with the atom, what happens to the energy. b) What could subsequently happen to the electrons in the higher energy levels help plz Yes energy = - 4.11E-17 J my mistake lol I think the answer is that the atom gets ionised and the remaining enegry becomes the KE of the free electron. but im confused as to the words 'what happens to the ENERGY' (is it just absorbed by the electron in the ground state and the rest goes to KE) and part b) i think it is the electrons drop down energy levels emmiting light - photons with discrete frequencies hence discrete wavelengths. but the questions says 'subsequently' , so im not sure if its right or is its just there to put you off.
