A body of mass x kg is moving with a velocity of 100 ms-1. Its de-Broglie wavelength is 6.62 × 10-35 m. Hence, x is (h = 6.62 × 10-34 Js)
0.1 kg
0.25 kg
0.15 kg
0.2 kg
The wave number of the spectral line in the emission spectrum of hydrogen will be equal to times the rydberg's constant if the electron jumps from
n =3 to n =1
n = 10 to n=1
n=9 to n=1
n = 2 to n=1
The set of quantum numbers for the outermost electron for copper in its ground state is
4, 1, 1 +1/2

Which one of the following sets of quantum numbers represents the highest energy level in an atom?
n = 4, l = 0, m = 0, s = +
n = 3, l = 1, m = 1, s = +
n = 3, l = 2, m = -2, s = +
n = 3, l = 0, m = 0, s = +
C.
n = 3, l = 2, m = -2, s = +
For highest energy level in an atom, (n + l) should be maximum.
