- The magnet in the following photo is made from neodymium, iron, and boron. A magnet mode of on alloy containing the elements Nd, Fe, and B. (a) Write the electron configuration of each of these elements using an orbital box diagram and noble gas notation. (b) Are these elements paramagnetic or diamagnetic? (c) Write the electron configurations of Nd3+ and Fe3+ using orbital box diagrams and noble gas notation. Are these ions paramagnetic or diamagnetic?arrow_forward6.49 Which of these electron configurations are for atoms in the ground state? In excited states? Which are impossible? (a) 1s22s1, (b) 1s22s22p3, (c) [Ne] 3s23p34s1, (d) [Ne] 3s23p64s23d2, (e) [Ne] 3s23p64f 4, (f) 1s22s22p43s2arrow_forwardThe following are orbital diagrams for presumed ground-state atoms. Several, though, violate Paulis principle or Hunds rule Which of the these follow both Paulis principle and Hunds rule, and which violate one or the other (state whether Paulis principle or Hunds rule is violated)? a b c d earrow_forward
- Which of the following electron configurations correspond to an excited state? Identify the atoms and write the ground-state electron configuration where appropriate. a. 1s22s23p1 b. 1s22s22p6 c. 1s22s22p43s1 d. [Ar]4s23d54p1 How many unpaired electrons are present in each of these species?arrow_forwardOne bit of evidence that the quantum mechanical model is correct lies in the magnetic properties of matter. Atoms with unpaired electrons are attracted by magnetic fields and thus are said to exhibit pararamagnetism. The degree to which this effect is observed is directly related to the number of unpaired electrons present in the atom. Consider the ground-state electron configurations for Li, N, Ni, Te, Ba, and Hg. Which of these atoms would be expected to be paramagnetic, and how many unpaired electrons are present in each paramagnetic atom?arrow_forwardFrom what you know in a general way about electron affinities, state which member of each of the following pairs has the greater value: a As, Br b F, Li.arrow_forward
- What type of electron orbital (i.e., s, p, d, or f) is designated by an electron with quantum numbers (a) n=1,l=0,m l =0(b) n=3,l=2,m l =1? (c) n=4,l=3,m l =3arrow_forwardA given orbital has a magnetic quantum number of m = 1. This could not be a(n) (a) f orbital (b) d orbital (c) p orbital (d) s orbitalarrow_forward
