Question

Quizplus · Accepted Answer

The mass number of an atom is the sum of its protons and neutrons. Therefore, the number of protons in the atom can be calculated by subtracting the number of neutrons (32) from the mass number (58):

protons = mass number - neutrons 
protons = 58 - 32 
protons = 26

So the answer is B)26, which represents the number of protons in the atom.
