the mass number of an isotope of uranium is 238, and its atomic number is 92. which symbol best represents this isotope of uranium?\no $_{92}u$\no $_{92}^{238}u$\no $_{238}^{92}u$\no $^{92}u$

the mass number of an isotope of uranium is 238, and its atomic number is 92. which symbol best represents this isotope of uranium?\no $_{92}u$\no $_{92}^{238}u$\no $_{238}^{92}u$\no $^{92}u$

Answer

Explanation:

Step1: Recall isotope notation

The notation for an isotope is $_{Z}^{A}X$, where $Z$ is the atomic number, $A$ is the mass - number, and $X$ is the chemical symbol.

Step2: Identify values for uranium isotope

For uranium, the chemical symbol is $U$, the atomic number $Z = 92$, and the mass number $A=238$.

Answer:

$_{92}^{238}U$
