Question

based on the periodic table block for nitrogen shown below, what nuclei notation would best represent the most common isotope of nitrogen? 7 n nitrogen 14.007

Explanation:

Step1: Identify atomic number

The atomic number ($Z$) of nitrogen from the periodic - table is 7.

Step2: Identify mass number

The most common isotope of nitrogen has a mass number ($A$) of 14 (from the average atomic mass value 14.007, and the most abundant isotope dominates the average).

Step3: Write nuclei notation

The nuclei notation is written as $_{Z}^{A}N$. Substituting $Z = 7$ and $A = 14$, we get $_{7}^{14}N$.

Answer:

$_{7}^{14}N$
