If lithium has a first ionisation energy of #520# #kJ# #mol^(-1)#, estimate the energy required to form 1 #Li^+# ion from 1 Li atom?
The ionization energy tells us that for 1 mole of gaseous lithium,
We also know that 1 mole contains
So, 1 atom =
We are given the first ionization energy of the lithium atom....
That is we are given data for the reaction:
And given the equation we need
To produce a SINGLE LITHIUM CATION, we divide the molar quantity by the Avocado number....the number of avocadoes in a mole,
