Question

Which is the correct electronic configuration of the element Mendelevium (Md)?

• A. $\left[Rn\right]5f^{14}7s^1$
• B. $\left[Rn\right]5f^{13}6d^{1}7s^1$
• C. $\left[Rn\right]5f^{13}6d^{0}7s^2$
• D. $\left[Rn\right]5f^{13}6d^{0}7s^2$

Answer 1

The correct option is C $\left[Rn\right]5f^{13}6d^{0}7s^2$

Mendelevium is a synthetic element with the symbol Md and atomic number 101.
${}_{101}Md{=}_{86}\left[Rn\right]5f^{13}7s^2$
