Which of the following has 61 neutrons,47 protons,and 46 electrons?

Question

Quizplus · Accepted Answer

To determine the element, we need to find the atomic number. Atomic number is the number of protons, which is given as 47 in the question. The element with atomic number 47 is silver (Ag).
To determine the number of neutrons, we subtract the atomic number from the mass number. The mass number can be calculated by rounding the atomic weight to the nearest whole number. The atomic weight of silver is 107.87, so the mass number is 108. The number of neutrons is 108-47 = 61.
The number of electrons is equal to the number of protons in a neutral atom, which is also 47 in this case.
Therefore, the correct choice is B, which represents an atom of silver (Ag) with 61 neutrons, 47 protons, and 46 electrons.
