The general valence shell electronic configuration of f-block elements is:

[noble gas] $(n - 2) f^{0, 1 - 14} (n - 1) d^{0 - 1} n s^{2}$ , where $n = 6$ in the case of lanthanides and $n = 7$ in the case of actinides.

Choose correct reaction (ignore balancing)

Note: Ln represents a lanthanide element

Answer:
