Which of the following describes an atomic property that makes some atoms useful for nuclear medicine applications and nuclear power generation? A.
Isotopes of an atom differ in the number of electrons they contain. Some isotopes are stable, and these are used in nuclear medicine and the generation of nuclear power.

B.
Isotopes of an atom differ in the number of neutrons they contain. Some isotopes are unstable, and these are used in nuclear medicine and the generation of nuclear power.

C.
Isotopes of an atom differ in the number of neutrons they contain. Some isotopes are stable, and these are used in nuclear medicine and the generation of nuclear power.

D.
Isotopes of an atom differ in the number of electrons they contain. Some isotopes are unstable, and these are used in nuclear medicine and the generation of nuclear power.

Oxidation-reduction reactions (often called "redox" for short) are reactions that involve the transfer of electrons from one species to another. oxidation states, or oxidation numbers, allow chemists to keep track of these electron transfers. in general, one element will lose electrons (oxidation), with the result that it will increase in oxidation number, and another element will gain electrons (reduction), thereby decreasing in oxidation number. the species that is oxidized is called the reducing agent or reductant. the species that is reduced is called the oxidizing agent or oxidant. to sum up: oxidation = increase in oxidation state = loss of electrons = reducing agent reduction = decrease in oxidation state = gain of electrons = oxidizing agent part a which element is oxidized in this reaction? fe2o3+3co→2fe+3co2 enter the elemental symbol. view available hint(s) is oxidized part b which element is reduced in this reaction? 2hcl+2kmno4+3h2c2o4→6co2+2mno2+2kcl+4h2o enter the elemental symbol. view available hint(s) is reduced
