the mass number of an isotope of uranium is 238, and its atomic number is 92. which symbol best represents this isotope of uranium?\n$_{92}u$\n$_{92}^{238}u$\n$_{238}^{92}u$\n$^{92}u$

the mass number of an isotope of uranium is 238, and its atomic number is 92. which symbol best represents this isotope of uranium?\n$_{92}u$\n$_{92}^{238}u$\n$_{238}^{92}u$\n$^{92}u$

Answer

Brief Explanations:

The standard notation for an isotope is to write the mass - number as a superscript and the atomic number as a subscript before the chemical symbol. Here, the mass number is 238 and the atomic number is 92 for uranium (U).

Answer:

<sup>238</sup><sub>92</sub>U (corresponding to the second option in the list you provided)
