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