Question

Quizplus · Accepted Answer

The given electron configuration is not standard notation and seems to contain errors or is presented in a non-traditional format. However, interpreting the intent behind "3d^5 4s^2" (assuming "S" and "U" are placeholders or errors in the text), the correct configuration that closely matches a real element is [Ar] 3d^5 4s^2, which is the electron configuration for manganese (Mn). Since the question does not provide a direct way to link this configuration to the provided options without a visual of the periodic table or additional context, and assuming a standard approach to interpreting the given configuration, the closest match based on common electron configuration notation would be an element with characteristics similar to manganese. However, without specific positions or a visual reference to "element A, B, C, or D" on the periodic table, the answer is inferred based on the provided electron configuration's resemblance to that of manganese.
