Interpretation: The second ionization energy of lithium is to be calculated.
Concept introduction:
Ionization energy is defined as the minimum energy needed to remove avalence electron from a neutral atom in the gaseous state.
The ionization energy is in
Answer to Problem 104AP
Solution:
Explanation of Solution
Given information:
The total energy required to remove all the three electrons from lithium is given as:
For lithium, the value of effective nuclear charge
Or
Substitute 3 for
In one mole, there are
So, the third ionization energy per mole is given as follows:
Since
Therefore,
Now, substitute
The second ionization energy of lithium is
