Question
Consider the spectral line resulting from the transistion n = 2 → n = 1 in the atoms and ions given below. The shortest wavelength is produced by
Options
A.hydrogen atom
B.deuterium atom
C.singly ionized helium
D.doubly ionized lithium
Solution
Shortest wavelength will correspond to maximum energy. As value of atomic number (Z) increases, the magnitude of energy in different energy states geta increased. Value of Z is maximum for doubly ionised lithium atom (Z = 3) among the given elements. Hence, wavelength corresponding to this will be least.
∴ Correct option is (d).
∴ Correct option is (d).
