Question

Which of following is not correctly matched?

• A. d-block element : electronic configuration is $n{s}^{0-2}(n-1)d^{1-10}$
• B. p-block element : electronic configuration is $n{s}^{2}n{p}^{1-6}$
• C. s-block element : electronic configuration is $n{s}^{1-2}$
• D. None of these

Answer 1

The correct option is A d-block element : electronic configuration is $n{s}^{0-2}(n-1)d^{1-10}$

Electronic configuration for d block element is $n{s}^{1-2}n-1d^{1-10}$

Hence the A is incorrect.
