Silver-109 has a mass of 109 amu. It is one of the isotopes of the silver atm.
<h3>What are isotopes?</h3>
The term isotopes has to do with the atoms of the same element that has the same atomic number but different mass numbers. This implies that the isotopes that we have do have the same number of protons but they do not have the same number of neutrons and the fact that they differ in the number of neutrons implies that would have the same chemical property.
We can see from the question that there are two isotopes of silver and tehse isotopes of silver have been identified as silver-107 and silver-109. The isotopes do have the same mass and not the same number of protons.
The percentage abundance of the two isotopes are not the same which means that one is more than the other. We can now see that the mass of the silver 109 in amu is 109 amu.

Answer:
Your correct answer is A. 1,2,1,2
Explanation:
Please mark brainliest!
An isotope is a chemical structure that is highly similar to its parent isotope, with the difference lying in the number of neutrons that the compound has. As an example, carbon has the elemental number 6, which means it has 6 protons. 12-carbon will have 6 protons and 6 neutrons, while 14-carbon will have 6 protons and 8 neutrons. The differing neutron numbers will have an affect on the nuclear reactions between these two compounds, but their chemical reactions will remain the same as the neutrons will not affect how they perform on a chemical level.
Answer:
Fe.
Explanation:
- The element which is oxidized is the element that losses electrons and its oxidation state be more positive.
- The element which is reduced is the element that gain electrons and its oxidation state be more negative.
<em> Fe goes from + 2 to +3, so, it is the element that is oxidized.</em>
