Which of the following is (are) correct for a H like species ?

Options

A. The energy gap between the consecative energy orbit decreases in the value of "n" increases
B. The longest wavelength in any spectral series corresponding to `alpha ` like in that series
C. Each spectral series is bounded by minimum and maximum wavelength and the rangy follow a contiaous distribution as given by bohr's theory
D. Kinetic energy of the electron decreases whereas the potential energy increases as the value of "n" increases

Explanation

a. Wrong Energy gap `= ((2n + 1))/(n^(2)(n+1)^(2))`
b. Wrong concpt of alpha line is used only in quentum mechanical treatment and not used in simple Bophr's thery for H like species
c. correct statement
d. Therefore PE with proper sing will increases with increase in value of a wherease KE will decreases
