Answer

Explanation:

Step1: Recall mass - number formula

The mass number (in amu) of an atom is the sum of the number of protons and neutrons. Mass number (A = p + n), where (p) is the number of protons and (n) is the number of neutrons.

Step2: Calculate mass number for atom A

For atom A, (p = 4) and (n = 4). So, (A_A=4 + 4=8) amu.

Step3: Calculate mass number for atom E

For atom E, (p = 5) and (n = 7). So, (A_E=5 + 7 = 12) amu.

Step4: Calculate mass number for atom G

For atom G, (p = 6) and (n = 7). So, (A_G=6+7 = 13) amu.

Step5: Calculate mass number for atom J

For atom J, (p = 12) and (n = 12). So, (A_J=12 + 12=24) amu.
