Answer:

e. none of the above.

Step-by-step explanation:

Hello there!

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


E=R((1)/(n^2_(final)) -(1)/(n^2_(initial)) )z^2

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:


E=2.178^(-18)J((1)/(2^2)} -(1)/(3^2) )1^2\\\\E=3.03x10^(-19)J

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

Regards!
