Comprehension An electron orbits a stationary nucleus of charge + ze where z is a constant and e is the magnitude of electronic charge. It requires 47.2 eV to excite the electron form the second bohr orbit to third bohr orbit. Angular momentum of electron in first Bohr orbit:
1.05 × 10(13 J(s
2.10 × 10(13 J-s
3.15 × 10(13 J-s
Can be (a) or (b)
Normal type of MCQ with one correct option Given that R is Rydberg’s constant. When an electron in an atom of hydrogen jumps from an outer orbit n = 3 to an inner orbit n = 2 , the wavelength emitted radiations will be equal to:
Comprehension An electron orbits a stationary nucleus of charge + ze where z is a constant and e is the magnitude of electronic charge. It requires 47.2 eV to excite the electron form the second bohr orbit to third bohr orbit. The radius of first bohr orbit is
