Answer:

e. none of the above.

Explanation:

Hello there!

In this case, according to the Rydberg's equation for the calculation of energy during electron transitions:

[tex]E=R(\frac{1}{n^2_{final}} -\frac{1}{n^2_{initial}} )z^2[/tex]

In such a way, we may assume that this element is H so z=1m the final energy level is 2 and the initial one is 3; thus, we plug in the values, and the Rydberg's constant to obtain:

[tex]E=2.178^{-18}J(\frac{1}{2^2}} -\frac{1}{3^2} )1^2\\\\E=3.03x10^{-19}J[/tex]

Thus, the answer is e. none of the above because the exponent is not given correctly.

Regards!
