A hydrogen atom in an excited state can be ionized with less energy than when it is in its ground state. What is n for a hydroge
Molodets [167]

Explanation:

It is known that formula for the ionization energy of hydrogen atom is as follows.

               E = \frac{13.6 eV}{n^{2}}

or,          n = \sqrt{\frac{13.6}{E}}

The value of energy is given as 0.544 eV. Therefore, we will calculate the value of n as follows.

                   n = \sqrt{\frac{13.6}{E}}

                      = \sqrt{\frac{13.6}{0.544 eV}}

                      = 5

Thus, we can conclude that n equals to 5 for a hydrogen atom if 0.544 eV of energy can ionize it.

PLZ HELP!<br><br> How do you think changing the angle of a ramp will affect work done?
kogti [31]

Answer: The steepness of a ramp affects it by making it easier or harder.

Explanation: It's a bit situational. If you were going up a steep ramp with a heavy load, it will increase the work necessary, whereas if you were going down a ramp, it would decrease the work necessary. If you need this simply put, think about biking up and down a hill. It would be easier going down than up.
