Question

Which block of the periodic table contains elements with the general electronic configuration?
$(n-2)f^{1-14}(n-1)d^{0-1}n{s}^2$

• A. s-block
• B. p-block
• C. d-block
• D. f-block

Answer 1

The correct option is D f-block

block	general electronic configuration
s	$n{s}^{1-2}$
p	$n{s}^{2}n{p}^{1-6}$
d	$(n-1)d^{1-10}n{s}^{1-2}$
f	$(n-2)f^{1-14}(n-1)d^{0-1}n{s}^2$
