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.
For the natural isotopes: - 107Ag has 60 neutrons - 109Ag has 62 neutrons
Silver-107 (51.35%) - 60 neutronsSilver-109 (48.65%) - 62 neutronsThe number of electrons is 47 in a neutral atom.
As silver atoms have 47 protons, the given isotope has 61 neutrons.

The term silver-96 indicates a mass number of 96 for that isotope of silver. The mass number of an isotope is the sum of protons and neutrons in the nuclei of its atoms. On the periodic table, the atomic number for silver is 47. The atomic number of an element is the number of protons in the nuclei of its atoms. The difference between the mass number and atomic number is the number of neutrons in the nuclei of the atoms of that isotope. In a neutral atom, the number of protons and electrons are equal. Therefore, silver-96 has 47 protons and 47 electrons in its atoms. The number of neutrons = 96 - 47 = 49.
For the natural isotopes: - 107Ag has 60 neutrons - 109Ag has 62 neutrons
there are 61 neutrons in a the element silver
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.
Silver-107 (51.35%) - 60 neutronsSilver-109 (48.65%) - 62 neutronsThe number of electrons is 47 in a neutral atom.
As silver atoms have 47 protons, the given isotope has 61 neutrons.
Hafnium is the element that has a mass number of 179. Its color is silver, its structure is hexagonal, while the number of neutrons is 106.
Number of Neutrons = Mass number - Number of Protons

On the periodic table, the atomic number for silver is 47. The atomic number of an element is the number of protons in the nuclei of its atoms. The difference between the mass number and atomic number is the number of neutrons in the nuclei of the atoms of that isotope. In a neutral atom, the number of protons and electrons are equal. Therefore, silver-96 has 47 protons and 47 electrons in its atoms. The number of neutrons = 96 - 47 = 49.
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.
Number of neutrons = mass number - number of protons
Two different isotopes of an element have different numbers of neutrons. That's what an isotope is. So, no, isotopes of an element can not have the same number of neutrons.
