Isotopes
Isotopes are atoms that have different number of neutrons, so they have a different mass number than the other atoms in an element.

What are the isotopes of cadmium?
See the link below, because cadmium has an enormous number of isotopes: 8 are natural, 30 are artificial.
What is an example of how ions and isotopes differ?
Ions involve differing numbers of electron orbiting the nucleus.
Isotopes involve differing numbers of neutrons in the nucleus.
How many protons neutrons and electrons are in an atom of 42 20Ca?
This isotope has 20 protons and and electrons and 22 neutrons.
What radioisotopes used for medical purposes they can be detected in the body by their radiation?
They are used for C.A.T. Scans for the Dye that is used when the Scan is being done. The dye is the "Isotopes", which alows the Tech, and the Doctor, to see the area, or area's that are highlighted, in a certain part of the Scan, that are affected. This is how they detect the problems, and are quick, to diagnose the problem.Some isotopes like Chromium-51 are used to label red-blood cellsand quantify gastro=intestinal protein loss.
What so two different neutral isotopes of the same element have in common?
Different Isotopes of the same element will each exhibit the same Chemical Characteristics.
What particle is involved most in the formation of an isotope?
In isotopes of a particular element, the number of neutrons differ where the number of protons and electrons remain same.
Are isotopes related to compounds?
Not directly. Isotopes are different forms of an element having different numbers of neutrons in their nucleus. But as different isotopes have the same chemical properties, they all can form the same compounds which function the same chemically.
If an element has one and only one stable isotope, an example is Gold.
How is a isotope of an atom different than a non isotope?
e.g.
Gold has 79 protons and 118 neutrons = 197 nucleons.
But some gold atoms are strange they only have 117 neutrons.
They are isotopes.
What does an isotope release as a beta particle?
Usually when isotopes undergo beta decay they emit an electron, but some isotopes emit a positron instead. This depends on the relative number of neutrons to protons in the isotope which type of beta particle is emitted. An excess of neutrons leads to the emission of an electron, while an excess of protons leads to the emission of a positron.
Does a radioactive isotope decay at a varying rate from the time it forms?
The probability of decay of any particular atom is a constant. However, as time passes, the there are fewer atoms left to decay. So in that respect the number of decay event falls.
What type of radiation is emitted when polonium forms lead-208?
Lead-208 is formed by alpha decay (emission of alpha particles) from polonium-212.
Does isotopes affect the physical properties of the element?
Isotopes contribute to the atomic weight of a chemical element.
The gamma radiation is very penetrant in biological tissues.
How many neutrons in C-13 in isotope?
Carbon 13 has 7 neutrons.
The atomic mass represents the total number of protons and electrons. Carbon atoms have 6 protons. Therefore, the atomic mass being 13, it has 7 neutrons.
How do you calculate the nuclear composition of isotopes?
The mass spectrometry is a method of evaluation.
Which phrase best describe radioactive isotopes?
Radioactive isotopes are atoms that have unstable nuclei and undergo radioactive decay, emitting radiation in the process. These isotopes are commonly used in various fields, such as medicine, industry, and research, due to their ability to deliver targeted energy and be detected easily.
Uranium-223 is an artificial isotope of uranium; some characteristics are:
- number of neutrons: 131
- type of decay: alfa, to 219Th
- atomic mass: 219,02774(8)
- half life: probable 21 microseconds
No radioactive isotopes of neon are ordinarily found in nature. All elements have radioactive synthetic isotopes, however.
Carbon-14, or radiocarbon, is a radioactive isotope of carbon with a nucleus containing 6 protons and 8 neutrons.
What are the activities or inactivates for the element curium as a gas or a solid?
The specific activities for some curium isotopes are:
- Cm-242: 3,3.10+3 Ci/g
- Cm-243: 4,2 Ci/g
- Cm-244: 82 Ci/g
- Cm-245: 0,1 Ci/g
- Cm-246: 0,36 Ci/g
What is most malleable fluorine potassium or silicon?
Potassium is the most malleable of these. However, there term can't be applies to fluorine, since it is a gas.
