Silver has 2 different naturally occurring isotopes:
The masses in amu differ from the mass number of the isotope because of the "mass defect, which in silver is slightly negative as is typical of elements in the middle of the binding energy curve. Also the mass of Silver on the Periodic Table of 107.912 amu is a weighted average the two isotopes masses. This is the number the chemist wants as he rarely cares about isotopes. If you want to count neutrons, you need a table of the isotopes of the elements, not just a periodic table. This is available in nuclear engineering, health physics, etc. texts.
The element of silver (Ag) has 47 protons in its nucleus. The number of neutrons in silver can vary depending on the isotope. For the most common isotope, Ag-107, there would be 60 neutrons.
As silver atoms have 47 protons, the given isotope has 61 neutrons.
Silver (Ag) has 47 electrons and a neutral atom of silver has 61 neutrons.
The element with 25 neutrons and a mass number of 47 is silver, with atomic number 47.

there are 61 neutrons in a the element silver
As silver atoms have 47 protons, the given isotope has 61 neutrons.
Silver (Ag) has 47 electrons and a neutral atom of silver has 61 neutrons.
Silver is an element on the periodic table with the symbol Ag. An atom of silver contains protons, neutrons, and electrons. The number of protons in a silver atom determines its atomic number, which is 47.
The element with 25 neutrons and a mass number of 47 is silver, with atomic number 47.
For any element, the atomic number is the number of protons in the nucleus. And for any element, the atomic mass is the number of protons plus the number of neutrons in the nucleus. For an element with the atomic number 47 and an atomic weight of 107, it will have 107 - 47 neutrons in its nucleus, or 60 neutrons in its nucleus. Whether or not an atom is a neutral atom or not makes no difference here.
neutrons
Number of Neutrons = Mass number - Number of Protons
108 - 47 = 61 neutrons 47 = atomic number of silver = number of protons
There are 62 neutrons in silver-107. Silver has an atomic number of 47, which corresponds to the number of protons in the nucleus. By subtracting the atomic number from the atomic mass, we can find the number of neutrons.
IsotopesThe number of protons in the nucleus of an atom determines the element. The number of neutrons can vary. If two atoms of the same element have a different number of neutrons in their nuclei, they are isotopes of that element.
