Explanation:
(a) The given data is as follows.
B =
Z = 4 for Be
Now, for the first excited state = 2; and
if it is ionized.
Therefore, ionization energy will be calculated as follows.
I.E =
=
Converting this energy into kJ/mol as follows.
= 5249 kJ/mol
Therefore, the ionization energy of the ion in its first excited state in kilojoules per mole is 5249 kJ/mol.
(b) Change in ionization energy is as follows.
=
or, =
Therefore, wavelength of light given off from the ion by electrons dropping from the fourth (n = 4) to the second (n = 2) energy levels
