Solve this multiple-choice question and choose the correct option.

Nuclear discoveries: Who discovered natural radioactivity? Identify the scientist associated with the 1896 discovery of spontaneous radioactivity in uranium salts. Choose the correct option.

Difficulty: Easy

Marie Curie
J. J. Thomson
Henri Becquerel
Ernest Rutherford

Correct Answer: Henri Becquerel

Explanation:

HistoryIn 1896, Henri Becquerel observed spontaneous emission from uranium salts fogging photographic plates, revealing natural radioactivity; Marie and Pierre Curie later isolated Ra and Po.
