Answer:
c.Therefore, we can say that the energy difference between adjacent orbit radii decreases with increasing values of the principal quantum number.
Explanation:
For the adjacent orbits or orbits that are one above the other
change in energy is given by
ΔE =[tex]13.6 [1/(n)^2 - 1/(n+1)^2 ][/tex]
where n= orbital number
so ,
now , if n value is increased,
value [ 1/(n)^2 - 1/(n+1)^2 ] will go on decreasing by clear observation as n is in the denominator
Therefore, The energy difference between adjacent orbit radii decreases with increasing values of the principal quantum number.
