Question

General electronic configuration of lanthanides is

• A. $(n-2)f^{1-14}(n-1)s^2{p}^6{d}^{0-1}n{s}^2$
• B. $(n-2)f^{10-14}(n-1)d^{0-1}n{s}^2$
• C. $(n-2)f^{0-14}(n-1)d^{10}n{s}^2$
• D. $(n-2)d^{0-1}(n-1)f^{1-14}n{s}^2$

Answer 1

The correct option is A $(n-2)f^{1-14}(n-1)s^2{p}^6{d}^{0-1}n{s}^2$

The general electronic structure of lanthanides is
$(n-2)f^{1-14}(n-1)s^2{p}^6{d}^{0-1}n{s}^2$
