Question

The ionization potential for the electron in the ground state of hydrogen atom is 13.6 eV atom^-1.What would be the ionization potential for the electron in the first excited state of Li2+

Answer 1

yes the ionization potential for the electrons in the ground state of hydrogen atom is 13.6 EV atom but first excited state of lithium 2 +

Answer 2

Answer: The ionization potential for the electron in the first excited state of $Li{2+}$ is 30.6 eV/atom

Explanation:

We are given ionization potential of the hydrogen atom which is 13.6 eV/atom.

To calculate the ionization potential for an atom, we use the formula:

$I.E.=13.6\times Z^2\left(\frac{1}{n_1^2}-\frac{1}{n_2^2}\right)$

where, Z = Atomic number = 3

$n_1$ = Lower energy level = 2

$n_2$ = Upper energy level = $\infty$

Putting values in above equation, we get:

$I.E.=13.6\times 3^2\left(\frac{1}{(2)^2}-\frac{1}{(\infty)^2}\right)eV/atom$

I. E. = 30.6 eV/atom
