Question

give the nuclear symbol for the isotope of argon for which ( a = 38 )? enter the nuclear symbol for the isotope (e.g., ( _2^4\text{he} )) using the stacked super/subscript template. view available hint(s) a chemical reaction does not occur for this question. submit

Explanation:

Step1: Recall nuclear symbol format

The nuclear symbol is in the form $\ce{_{Z}^{A}X}$, where $A$ is mass number, $Z$ is atomic number, and $X$ is element symbol.

Step2: Find atomic number of argon

Argon (Ar) has atomic number $Z = 18$ (from periodic table).

Step3: Construct nuclear symbol

Given $A = 38$, $Z = 18$, element is Ar. So symbol is $\ce{_{18}^{38}Ar}$.

Answer:

$\ce{_{18}^{38}Ar}$
