Question

determine the number of protons and neutrons in each isotope.
a. $_{7}^{14}n$

Explanation:

Step1: Recall atomic number and mass - number meaning

The atomic number ($Z$) is the number of protons and is given as the subscript. The mass number ($A$) is the sum of protons and neutrons and is given as the superscript. For $_{7}^{14}\text{N}$, the atomic number $Z = 7$ and the mass number $A=14$.

Step2: Calculate the number of protons

The number of protons is equal to the atomic number. So, the number of protons $p=7$.

Step3: Calculate the number of neutrons

The formula for the number of neutrons ($n$) is $n = A - Z$. Substituting $A = 14$ and $Z = 7$, we get $n=14 - 7=7$.

Answer:

Number of protons: 7
Number of neutrons: 7
