¿Cuál es el elemento número 61 de la tabla periódica?<end_of_turn>
<start_of_turn>model
The 61st element of the periodic table is Promethium (Pm). As a member of the lanthanide series, promethium is a rare and unique element with limited practical applications due to its rarity and radioactivity. It is a soft, silvery-white metal that glows faintly in the dark due to its radioactivity. One of the few applications of promethium is luminous paint for certain types of watch dials and dashboards, where its radioactivity contributes to the glow-in-the-dark effect. However, due to its radioactivity and limited availability, promethium is not commonly used in everyday products. It is primarily used for research purposes and in some specialized devices that require a radioactive source for various applications, such as thickness gauges and atomic batteries. Challenges posed by its radioactivity and rarity have limited promethium's broader commercial applications, but its unique properties continue to find niche uses in specific technologies.<end_of_turn><eos>
