## How do you calculate the ionization energy of lithium?

Solution: For `3^(Li^(7))` atom, `Z=3, n=2 [because Li =1s^(2) 2s^(1)]` <br> `E_(n)=(13.6Z^(2))/(n^(2))eV` <br> “=(13.6xx(3)^(2))/(4)=30.6 eV” <br> `hence` ionization energy of lithium =30.6 eV.

## How do you find the ionization energy of li2+?

also IE li^2+= 13,6 × 9 = 122 .

## What energy level is li2+?

The energy level of the lithium ion is n=4 .

## What is the energy of lithium atom?

The binding energy of an electron in Li-ion in the ground state is 75.6 eV.

## What is second excitation energy of Li2+?

E = 13,6 × 8. E = 108,8 eV.

## Which energy level in Li 2 +) has same energy as the fourth energy level of H atom?

Answers. Hence n = 12 Ans.

## What should be the first excitation potential of Li2+?

Answer: The energy of the first excited state is -30.6 eV. That means it has 3 electrons.

## How do you find the energy level of an element?

If you look at the periodic table of the elements, the energy levels of the atoms correspond to the rows of the table. The two elements in the top row, hydrogen and helium, fill their first energy level with their end electrons. The eight elements of the second row fill their second energy level.
