Quizplus · Accepted Answer

The given number, 11ea8937_ab52_fafa_a16d_2fb35308b277_TB4499_11, represents the atomic number of an atom, which is 123456. The number of neutrons in an atom can be determined by subtracting the atomic number from the mass number. Since the mass number is not provided, we need to look for an answer choice that differs from the given atomic number by a multiple of the number of neutrons. Option B has an atomic number of 123455, which differs by one from the given number. This suggests that the mass number of the atom is one more than the given atomic number, which means that it has one more neutron than the given atom. Therefore, option B is the correct answer.
