do u have to know about the transistors,diodes,triodes etc in terms of their structure? or is it enough just to know their advantages and disadvantages etc

thnx, it would be appreciated.

oh ok thnx for the help

im not sure wat the conduction band is. is it a level that forms b/w electrons, or is it an imaginary level that is used in symbolising the conductivity of the material? if its neither please tell me thankyou

yeah it all seems right. the valence band is full of electrons at absolute zero, and that the conduction band is empty.

these are straight from som1's notes from phys resources. they seem to explain the process very well • Soft tissue anatomy is not very clear with standard x-ray radiography. Clarity is markedly increased by using x-rays and computers together in computed axial tomography. The word...

thnx for the reply ill try n work out whether or not i fit under that category

i would like to know if anyone here made it into medicine at newcastle uni. i really want to pursue this course and would appreciate any help on ways to go about the umat exam and how to tackle the interviews. thnx

Conduction electrons are free electrons that are not bound to the nucleus. Only bound electrons satisfy the condition of standing waves. In any case if these electrons were standing waves they would never give off energy. They would be superconductors! X-rays generated are not powerful enough...

i dont think such rude comments are neccessary he asked a decent question i think u should apologise

85% 5th in the grade

maybe sum1 else can explain it in better terms

i think it supported the wave theory at the time but the reason that no deflection was seen was because this was due to the rays themselves. i.e. within the tube, the cathode rays ionized the gas. The ions were attracted to the plate with the opposite charge and the line-up of ions effectively...

hmmmm...... good question

do u hav to name a chemist or is it the role of a chemist in general

lol i barely know how to turn my computer on let alone use it to hack into the schools one. maybe sumtime in the future. just let me read a book on it it couldnt be that hard

same here

see wat i mean by a headache

so its not: 2-hydroxy-1,2,3-propanetricarboxylic acid

the notes by John Marsden are also pretty good for this dot point graphs and all
