Question
tion will result in the emission of a photon with the lowest energy from a hydrogen atom? a)2s4s b)3s-* 4s c) 4p 1s c) 5s 3s 6. I1 pt/Which statement best explains why an atom of chlorine is smaller than an atom of sodium? Xa) Sodium has fewer valence electrons. xb) Both atoms have the same number of core electrons but chlorine has more valence electrons. c) The valence electrons in chlorine experience a greater effective nuclear (Corel charge. d) Chlorine's valence electrons experience more shielding than those of sodium. e) Sodium has more electron-electron repulsion in its valence shell 7. B pts) Choose the orbital energy level diagram that represents the ground state of osygen (O) b. d. 2s 2s 2s 1s 8 3 ptsj)Which selection best describes the magnetic properties of T? To receive full points you must show the corect orbital dingram (condensed is OKj) for Ti in the space provided a) diamagnetic c) need more information to determine d) both paramagnetic and diamagnetic Orbital Diagram for Ti 3 S 2 SExplanation / Answer
5. lowest eenrgy, means eenrgy gap between energy levels must be minimum.
so that, answer: e) 5s --> 3s
6. answer: c ,
in periods left to right,effective nuclear chargeincreases,atomic radius decreases.
7. answer: c
O = 8 = 1s2 2s2 2p4
8. Ti = 22 = [Ar]4s2 3d2
in 3d-orbital , there are two unpaired electrons.so that,it is paramagnetic.
answer: b
