Is there a particular way to measure or find the radius of an ion?

i dont know, there should be ... but i do know that we dont need to know We'll just have to use values from the data booklet if we have to ... all hard work done by someone elseIs there a particular way to measure or find the radius of an ion?
are they taking the ratio of the changes or sth? Coz Chlorine's oxdn state is decreasing by 2 and Sulphur's by 4 ...
Actually this equation is given wrong here :3
So they will be in data bookleti dont know, there should be ... but i do know that we dont need to know We'll just have to use values from the data booklet if we have to ... all hard work done by someone else
I guess.So they will be in data booklet
Great ^_^
N abt the ionic radius
Its the distance b/w the nuclues and the outershell if the ion
Am i ryt?
OkI guess.
You should know what energies to use in the born-haber cycle. And to find lattice energy,Ok
N how do we find if we have to add up all energies given in Born haber cycle or subtract them to find lattice energy ?
HmmYou should know what energies to use in the born-haber cycle. And to find lattice energy,
Latt energy change = Enthalpy change of formation - (the sum of rest of the energies you use in the cycle)
You will understand better if you try a past paper question on this.
Thanks buddy tho i do edexcel not ciezahra azam ... you could try 42/m/j/14 - Q2d
Is edexcel easier than cie?Thanks buddy tho i do edexcel not cie
I will say both stand on the same levelIs edexcel easier than cie?
Nope ... don't get yourself confused like that with a particular formula. If you draw the Born-Haber cycle (I hope you know how to?) you will see what needs to be added and subtracted with the arrows ... and this cycle is just a more advanced version of Hess'law so you can can just take the different routes and well, you know, calculate whatever energy you want.Hmm
Is it not like lattice energy and the electron affinity= rest of energies on the left side?
If you can, find a question in edexcel and do ... or it wouldn't hurt to do this as well ... just practice so you can understandThanks buddy tho i do edexcel not cie
Yep thankfully i do know how to draw it xDNope ... don't get yourself confused like that with a particular formula.

coolYep thankfully i do know how to draw it xD
Yep i did one of the qs in my book ur way
It works
Thanks
