Edexcel AS Chemistry 1 - Structure and bonding discussion.

I'm doing it, but no problems Are you doing it? or are you passed this and are helping ? :P

Is the first ionisation energy the energy required to remove the most loosely held electron from one mole of gaseous atoms to produce 1 mole of gaseous ions each with a charge of 1+?
Just want to check this.

Yup sounds good to me! Do you have to be able to produce the graph of first ionisation energies?

yes
what is the second ionisation?
why is the second inonisation energy of a sample of sodium atoms much higher than the first?

what is the defenition of first electron affinity?

Im doin edexcel a well but w havent covered much..I have 2 teacher. All Ive covered is S-Block stuff and the halogens. But Im gonna start D-block and mole concept soon.
Quite interestin and quite a step up from Gcse but nothin too tricky.
How are you gonna revise for it by the way??

Electron affinity is the reverse of ionisation energies in the sense instead of removing an electron we are addin an electron. This varies as we go across the group in the opposite kinda direction but we need 2 consider repulsion in Grp 7 element which actually reduces the energy required.
Sodium question is about once the uinitiall electron has been removed it has a noble gas config. therefore has a large ionisation energy majiggy

here are some revision questions for those taking in January (atomic structure only)
Define relative atomic mass.
Define relative isotopic mass.
Why is the second electron affinity always endothermic?
What is an isotope?
State four processes in the mass spectrometer.

I dont wana answer all the questions jst incase someone els wants to ansa.
We havent looked at elctron affinity at all so Im not sure about that(Why is the second electron affinity always endothermic?) care to ansa unless someone els wants to...
Isotopes same no of protons different no. of neutrons. Same atomic mass dif mass no.
Stages of mass spectrometer.Ionisation.Acceleration.Deflection.Detection.(im not sure coz there are more smaller parts of the process)

How are you findin the course so far by the way?? did you find mole concept hard or not... you enjoy chem?
Do you kno where to find any specimen papers.. I was gonna get some of the old ones but apparently they are to make the exam more diffilcult because ppl sed it was too easy last year (at least according to my teacher).
