ATOMIC STRUCTURE(QUIZ-5) 1 / 5 When α-particles are sent through a thin metal foil, most of them go straight through the foil because α-particles are much heavier than electrons α-particles are positively charged Most part of the atom is empty space 𝛼-particles move with high velocity When α-particles are sent through a thin metal foil, most of them go straight the foil because most part of the atom is an empty space. 2 / 5 How many spherical nodes are present in 4s orbital in a hydrogen atom? 0 2 3 4 Number of nodes=𝑛−𝑙−1=4−0−1=3 3 / 5 Which of the following orbital does not make sense? 3𝑑 2𝑓 5𝑝 7𝑠 For𝑓orbital,𝑙 = 3, here 𝑛 = 2But 𝑛 < 𝑙 4 / 5 Which electronic level would allow the hydrogen atom to absorb a photon but not to emit a photon? 3𝑠 2𝑝 2𝑠 1𝑠 The lowest energy state is 1𝑠. It is not possible from this state to lose energy 5 / 5 Which of the following related to photons both as wave motion and as a stream of particles? Interference 𝐸=𝑚𝑐2 Diffraction 𝐸=ℎ𝑣 For photon, 𝐸 = ℎ𝑣 (in form of particle and wave) Your score isThe average score is 80% 0% Restart quiz
