A neutral atom of silver must also have <strong>47 electrons<\/strong> to balance the positive charge of the protons.<\/p>\n\n\n\n<p>The <strong>mass number<\/strong> of an isotope represents the sum of protons and neutrons in the nucleus. The most common isotope, <strong>Ag-107<\/strong>, has a mass number of <strong>107<\/strong>, so the number of neutrons is calculated by:<\/p>\n\n\n\n<p>[<br>\\text{Neutrons} = \\text{Mass Number} &#8211; \\text{Atomic Number} = 107 &#8211; 47 = 60<br>]<\/p>\n\n\n\n<p>Similarly, for <strong>Ag-109<\/strong>, the isotope has a mass number of <strong>109<\/strong>, meaning the neutron count is:<\/p>\n\n\n\n<p>[<br>\\text{Neutrons} = 109 &#8211; 47 = 62<br>]<\/p>\n\n\n\n<p>The only difference between Ag-107 and Ag-109 is the <strong>number of neutrons<\/strong> in the nucleus. Ag-109 has <strong>two more neutrons<\/strong> than Ag-107. However, both isotopes have the same <strong>chemical properties<\/strong> because chemical behavior is determined by <strong>electrons<\/strong>, and both have 47 electrons.<\/p>\n\n\n\n<p>Physically, the extra neutrons in Ag-109 make it slightly <strong>heavier<\/strong> than Ag-107. These isotopes can be distinguished using techniques like <strong>mass spectrometry<\/strong>. The different isotopes may also affect nuclear stability and reaction behavior in some cases, but for silver, both Ag-107 and Ag-109 are stable isotopes.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Silver has an atomic number of 47. a.
