Question

Which electron transition would result in the greatest amount of energy to be absorbed? a) n = 4 to n = 1 b) n = 1 to n = 4 c) n = 2 to n = 1 d) n = 1 to n = 3 e) None of the choices are correct

Answer 1

Answer:

b) n = 1 to n = 4.

Explanation:

a ) n = 4 to n = 1 transition represents release of energy because transition is from high energy orbit to low energy orbit.

Similarly c) n = 2 to n = 1 represents release of energy because transition is from high energy to low energy orbit.

d ) n = 1 to n = 3 is also energy absorbing transition but amount of energy absorbed is less as compared with option b) transition .

So the correct option is b)
