Ionization energy of a hydrogen like A is greater than that of another hydrogen like ion Let r, u, E and L represent the radius of the orbit, speed of the electron energy of the atom and orbital angular momentum of the electron respectively, in ground state

Options

A. (i), (ii)
B. (ii), (iii)
C. (i), (iii)
D. (ii), (iv)

Answer

D

Explanation

`Z_(A)^(2) gt Z_(B)^(2) implies Z_(A) gt Z_(B)`
`r prop (1)/(Z) implies r_(A) lt r_(B)`
`u prop Z implies u_(A) gt u_(B)`
`E_(n) =-13.6(Z^(2))/(n^(2))`
` E_(n) prop - Z^(2) implies E_(A) gt E_(B)`
`L prop Z^(@) implies L_(A)=L_(B)`
