Using the periodic table, predict which element is likely to have the ground-state electron configuration [Xe]6s²4 $ f $ ¹⁴5d⁵?

Question

Quizplus · Accepted Answer

The given electron configuration is a distorted representation of the ground-state electron configuration for rhenium (Re). The correct configuration for Re, which is [Xe]4f^14 5d^5 6s^2, seems to have been obfuscated with placeholders like "S1U1P1" instead of actual electron counts. Rhenium is the element that fits this configuration pattern, placing it in the 5d block of the periodic table.
