Lanthanides Flashcards
(4 cards)
1
Q
4f orbitals
A
3 angular nodes, no radial, u symmetry, limited crystal field effect
2
Q
lanthanide contraction
A
Zeff increases across series, f-orbitals have poor shielding of nuclear charge so atomic radii decreases across series
3
Q
solid state structures of Ln3+
A
9 = tricapped trigonal pyramidal
8 = bicapped trigonal pyramidal
6 = octahedral
4
Q
particle radiation
A
a = He atoms, held together by strong nuclear force
B = electrons
positron emission
neutrons
