Answer

Explanation:

Step1: Recall mass - number formula

The mass number of an atom is the sum of the number of protons and neutrons ($A = p + n$), where $A$ is the mass number, $p$ is the number of protons, and $n$ is the number of neutrons. The number of electrons does not contribute to the mass of the atom.

Step2: Calculate mass - number for atom 1

For atom 1, $p = 39$ and $n=52$. So, $A_1=p + n=39 + 52=91$.

Step3: Calculate mass - number for atom 2

For atom 2, $p = 40$ and $n = 50$. So, $A_2=p + n=40+50 = 90$.

Step4: Calculate mass - number for atom 3

For atom 3, $p = 39$ and $n = 50$. So, $A_3=p + n=39+50 = 89$.

Step5: Calculate mass - number for atom 4

For atom 4, $p = 40$ and $n = 54$. So, $A_4=p + n=40+54 = 94$.
