∙ 16y agoAg-107 and Ag-109 are the two common isotopes of silver. There are nearly a dozen known isotopes of silver, but all are radioactive and decay quickly (in half-life lengths from 24.6 seconds to 41.3 days) into something else, except for the two stable isotopes, 107 and 109. Chemically, all isotopes of silver behave the same, and all are indeed silver. It is only their atomic masses that are different. Ag-107 has 47 electrons, and its nucleus contains 47 protons and 60 neutrons, for an Atomic Mass of 106.9. Ag-109 has 47 electrons, and its nucleus contains 47 protons and 62 neutrons, for an atomic mass of 108.9. Natural silver consists of about 51.8% Ag-107 and about 48.2% Ag-109, for an average atomic mass of about 107.9. Any silver you are likely to have - jewelry, bullion, coins, or whatever - consists of these ratios of these isotopes. http://www.webelements.com/webelements/scholar/elements/silver/nuclear.html

What is the mass of an atom found by?
Mass of an atom = Mass of proton + Mass of neutron
Mass by difference?
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
What is the formula for mass percent?
mass % of element X = mass of element X ____________________ X 100 total mass of compound or mass of solute _____________________________ X 100 mass of solute + mass of solvent
What is the mass percent composition of an element in a molecule?
Percentage composition= (mass of the element/mass of the molecule)*100 The fraction of the molecule's mass that comes from the element's mass
What is relationship between the formula weight of a substance and its molar mass?
Molar mass is the mass of particles in one mole of a substance. Molar mass is equal to atomic/ molecular/ formula mass in amu. Formula mass is in atomic mass unit while molar mass is in grams .
How many electrons does Ag109 have?
178456
What is the amount of matter in an object?
Its mass.
How is mass different from mass?
Mass and mass are the same thing.
How do you find a mass by difference?
Mass of the contained material = Total mass (mass of the container + mass of the material) - Mass of container
Does mass have mass?
Yes, mass has mass. It is, therefore, matter. If mass did not have mass, then it is "something" with no mass. That would make it "non-matter" and perhaps it might be energy.
What properties stay the same during physical and chemical change?
mass mass
How about air and mass.do they have mass?
Air has mass. Mass is a property and does not have mass
What is the mass of an atom found by?
Mass of an atom = Mass of proton + Mass of neutron
What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
How do you solve for percent by mass?
reg.% by mass mass% m/m mass of solute mass of solution=x100
What are the three other names for Midnight Mass Dawn Mass and Christmas Day Mass?
Angel's Mass, Shepherd's Mass, and Mass of the Divine Word.
Mass by difference?
mass by difference is an indirect way to find the mass of an object. For example, if you know the mass of a 'beaker and the substance in it' and the 'mass of the beaker', you can determine the mass of the substance by subtracting (mass of beaker + substance) - (mass of beaker)
