Calculation of Energy of Ground Level in Doubly Ionized Lithium
To calculate the energy of the ground level in doubly ionized Lithium, we need to use the formula:
E = -Z2 (13.6 eV)
where E is the energy of the ground state, Z is the atomic number of the element, and 13.6 eV is the ionization energy of hydrogen atom.
Step 1: Calculate the Atomic Number of Doubly Ionized Lithium
Lithium is a three-electron atom. When it is doubly ionized, it loses two electrons and becomes a one-electron atom. Therefore, the atomic number of doubly ionized lithium is:
Z = 3 - 2 = 1
Step 2: Calculate the Energy of the Ground State
Using the formula above, we can calculate the energy of the ground state of doubly ionized lithium:
E = -12 (13.6 eV) = -13.6 eV
However, this is the energy of the ground state of singly ionized lithium. For doubly ionized lithium, we need to subtract another 13.6 eV, since it has lost two electrons.
E = -22 (13.6 eV) = -54.4 eV
Therefore, the energy of the ground level in doubly ionized Lithium is -54.4 eV.
Conclusion
The energy of the ground level in doubly ionized Lithium is -54.4 eV. This is calculated using the formula E = -Z2 (13.6 eV), where Z is the atomic number of the element and 13.6 eV is the ionization energy of hydrogen atom.
