The atom has the greatest mass is: B. an atom with 8 protons, 8 neutrons, and 8 electrons.

Mass number is also referred to as atomic mass number and it is the total number of protons and neutrons found in an atomic nucleus.

Mathematically, mass number is given by the formula:

[tex]A = Z + N[/tex]

Where:

  • A is the mass number.
  • Z is the atomic number or number of protons.
  • N is the number of neutrons.

Substituting the given parameters into the formula, we have;

For option A;

Z = 8, N = 7

[tex]A = 8 +7=15 \;amu[/tex]

For option B;

Z = 8, N = 8

[tex]A = 8 +8=16 \;amu[/tex]

For option C;

Z = 9, N = 6

[tex]A = 9 +6=15 \;amu[/tex]

For option D;

Z = 7, N = 8

[tex]A = 7 +8=15 \;amu[/tex]

Therefore, an atom with 8 protons, 8 neutrons, and 8 electrons has the greatest mass number.
