(c)
1. False. The configuration is
2. False. The wavelength of gamma rays is of the order of m
3. True. In hydrogen atom, the energy of an electron depends only on the principal quantum number of the orbital which it occupies
False. In -plane, there is no electron density if an electron occupies orbital
