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

Which isotope of what element? We need a little more information here in order to be able to help you. However, the most common isotope of Oxygen has 8 neutrons. I hope this answers the question. If not, please try resubmitting with more information.
An isotope is unstable if the ratio of protons to neutrons in its nucleus is not optimal. This imbalance can lead to excessive nuclear energy, causing the isotope to decay in order to achieve a more stable configuration. Factors like excess energy, suboptimal nuclear forces, and high neutron-to-proton ratios contribute to the instability of isotopes.
What isotope of uranium has less than 3 neutrons?
None, no element beyond lithium can have a stable isotope with as few as 3 neutrons. If by some happenstance a uranium nucleus did form with as few as 3 neutrons (this would be U95) it would instantly burst apart in a flash of protons before it could even be detected.
At what point do isotopes stop decaying?
Isotopes do not stop decaying. The process of radioactive decay continues until the isotope reaches a stable state, which could be a different isotope or a non-radioactive element. The rate of decay can vary depending on the specific isotope.
Why are radioactive isotopes and half life important to science?
Radioactive isotopes are important because they can be used as tracers in medicine and industry, and in dating rocks and fossils. The concept of half-life is important because it allows scientists to predict how long it will take for a radioactive material to decay to half its original amount, which is crucial for understanding processes like nuclear decay and radioactive dating.
What do isotopes' differences depend on?
Isotopes depend of the number of neutrons in the nucleus.
The number of protons will always remain the same for that particular element. The number of neutrons may vary because they do not affect the charge, but rather its weight. This is why we have peculiar numbers for the average atomic mass, because some elements have different isotopes and based on how common they are will affect its average atomic mass.
Uranium and radon share the property of radioactivity which means?
they both spontaneously emit radiation in the form of alpha, beta, or gamma rays. This radiation can damage living tissue and increase the risk of cancer if exposure is prolonged. Both substances are radioactive and undergo radioactive decay over time.
Why are the ionisation energy of isotopes the same?
The ionization energy of isotopes is the same because isotopes have the same number of protons in their nucleus, which determines the ionization energy. Isotopes differ in the number of neutrons they possess, but neutrons do not contribute significantly to the ionization energy compared to protons.
Is an isotope a chemical property?
An isotope is not a chemical property; rather, it refers to different forms of an element that have the same number of protons but different numbers of neutrons. Isotopes can affect the physical properties of an element, such as its mass and stability, but they do not change its chemical properties.
Is an isotope an atom with a positive charge?
No, an isotope is an atom with the same number of protons but a different number of neutrons. A positive charge on an atom would indicate it has either lost electrons or gained protons.
What is the difference between the parent isotope and the daughter isotope?
The parent isotope is the original radioactive isotope that undergoes decay to form the daughter isotope. The daughter isotope is the stable isotope that is formed as a result of the radioactive decay of the parent isotope.
Are isotopes of an element charged particles?
No, that's an ion. An isotope is an atom of the same element with a different number of neutrons.
Is lithium an isotope ion or neutral atom?
Lithium is two of these but at the same time neither. It's an element.
It is best described as an element, a type of atom with unique properties. If the number of neutrons varied, the multiple lithium atoms would be called isotopes. As for neutral vs. ion, if the number of protons is equal to the number of electrons, it is neutral. If it is not, it is an ion, specifically anion (less protons) or cation (more protons). It will always be a neutral atom or ion.
It will always be an isotope, but only called so when in a group of lithium atoms with various numbers of neutrons.
What is the top number in an isotope?
An isotope is identified by atomic number (element number or name), by mass number, and by atomic weight. The mass numberfor an isotope is listed as a leading superscript such as 29Si, which in this example is silicon containing 14 protons and 15 neutrons (a rarer but stable isotope of the element). Similarly the atomic weight is indicated by a superscript such as U235 , an isotope of uranium having 92 protons and 143 neutrons.
The actual atomic weight is often expressed as a decimal number corresponding to the mass of the atom in "atomic units", where a proton is about 1.0072, a neutron 1.0086, and an electron about .00055 atomic units.
What are the atomic number and atomic mass of the isotope Br 79?
The atomic number of any bromine atom is 35, and the atomic mass number is the number stated after the element name in the question, in this instance 79.
What isotope is best for dating very old rocks?
Uranium-lead dating is often used for dating very old rocks, as it has a long half-life of about 4.5 billion years. This allows for dating rocks that are millions to billions of years old with good accuracy.
Can isotopes be used for human diagnosis?
Yes, isotopes can be used for human diagnosis through a technique called isotope imaging. Isotopes can be injected into the body and tracked using imaging technology to reveal information about the body's functioning or detect abnormalities, such as in nuclear medicine procedures.
What are some common isotopes of silicon?
Natural isotopes of silicon are:
28Si - 92,23 % (stable)
29Si - 4,67 % (stable)
30Si - 3,1% (stable)
31Si - traces (radioactive, unstable)
32Si - traces (radioactive, unstable)
Now many isotopes in oxygen-16?
Oxygen-16 IS an isotope of oxygen. If you meant to ask the number of isotopes of oxygen, the answer is 3. They are Oxygen-16, -17 and -18.
Oxygen-16 is the most abundant of the isotopes.
Does fluorine have many isotopes?
Fluorine has an atomic number of 9 and a relative atomic mass of 18.998 403 2(5). This means that it has 9 protons (atomic number). 18.998 403 2(5) is very close to 19 which means that most fluorine atoms have 19 protons and neutrons (added together). Since we already know there are 9 protons there must be 10 neutrons in most fluorine atoms (19-9=10).
Does ogygen have any isotopes?
Yes, oxygen has three naturally occurring isotopes: oxygen-16, oxygen-17, and oxygen-18. Oxygen-16 is the most abundant, making up about 99.76% of naturally occurring oxygen.
What are the isotope of hydrogen?
Protium (1H), Deuterium (2H), and Tritium (3H) are the three isotopes of hydrogen.
Only the first two occur naturally, the third can only be produced in nuclear reactors or nuclear bombs typically from lithium.
* Hydrogen (1H)
* Deuterium (2H or D)
* Tritium (3H or T)
* 4H
* 5H
* 6H
* 7H
Hydrogen, deuterium and tritium atre natural isotopes; isotopes 3H-7H are radioactive and unstables.
Isotopes do not have a specific charge, as their charge is determined by the number of protons and electrons they possess. Neutral atoms have an equal number of protons and electrons, resulting in no overall charge. However, isotopes of an element can have different numbers of neutrons, which does not affect their charge.
What are the subatomic particles in the isotope CA?
The question is worded a little strangely, but if the alternate wording is correct I can answer.
Calcium 45 has 20 Protons (like all calcium isotopes) and 25 Neutrons. That makes 65 up quarks and 70 down quarks.
Electrons may vary with ionization, but will typically be 20.
The phenomenon in which different compounds have the same molecular and structural formula, but different geometry due to different spatial arrangement of groups with respect to a double bond or a ring is called as geometric isomerism.
