[edit] Notes
- Values marked # are not purely derived from experimental data, but at least partly from systematic trends. Spins with weak assignment arguments are enclosed in parentheses.
- Uncertainties are given in concise form in parentheses after the corresponding last digits. Uncertainty values denote one standard deviation, except isotopic composition and standard atomic mass from IUPAC which use expanded uncertainties.
List the isotopes used in agriculture?
There are far too many isotopes of different elements to list them here. Just as one example, most hydrogen is 1H, but 2H is the hydrogen in deuterium, which has several industrial uses. A more specific question will get a more specific answer.
Is the element with atomic number eight an isotope?
The element with atomic number eight is oxygen, and anyatom of oxygen is an isotope. Let's see how that works.
The word isotope speaks to the number of neutrons in a given atom of a given element. When we speak of oxygen, we might consider any of its isotopes, but all atoms of this element have eight protons in their nucleus. They're all oxygen, and all have atomic number eight. Oxygen has three stable isotopes, and they are O-16, O-17 and O-18. All atoms of these isotopes have eight protons in them, but they have eight, nine and ten neutrons in their nuclei, respectively.
An element has 22 protons 20 electrons and 26 neutrons What isotope is it?
The element with 22 protons is titanium (Ti). The sum of protons and neutrons determines the isotope, so with 26 neutrons, the isotope is titanium-48 (22 protons + 26 neutrons = Ti-48).
Why do isotopes of the same element have the same chemical behavior?
- Chemical properties of a element is governed by ELECTRONIC CONFIGURATION of that element. As isotopes of same element have identical electronic configurations, their chemical properties are same.
What are the everyday uses of an isotope?
The everyday uses of an isotope include food irradiation, medical applications, archaeological dating, and in instruments like smoke detectors. Some medical uses are for bone imaging and radiation therapy for cancer.
What are the common isotopes of Rhodium?
The common isotopes of Rhodium are Rh-103, Rh-101, Rh-102, Rh-102m and Rh-99. They also happen to be stable. In addition to these isotopes, there are 30 other Rhodium isotopes.
Different isotopes have different what?
The isotopes of an element must have a different amount of neutrons.
I'm pretty sure you know what these are, but just in case:
A neutron is a sub-atomic part of an atom, together with protons and electrons.
How are all of the isotopes of an element similar?
by having the same number of protons and electrons and so still have the same chemical properties and physical properties with the exception of being somewhat denser.
All of the isotopes of an element contain the same number of protons. They differ only in the number of neutrons.
The number of electrons is an ionization state issue, and does not affect isotopic identity.
Why must different isotopes of the same element have different physical properties?
Isotopes are atoms of an element having different numbers of neutrons. The atomic mass of an atom is approximated by the number of neutrons plus the number of protons; it follows, then, that isotopes of an element differ in their atomic masses.
Mass itself is a physical property. Other properties related to mass also vary by isotope: density (mass/volume), boiling point, freezing point, and the degree of ion deflection in a mass spectrometer are perhaps the most obvious of these related properties. The rate of diffusion is also affected; as per Graham's law of effusion, the rate of diffusion of a gas is inversely proportional to the square root of its molecular mass. (This property played a crucial role in the development of the atomic bomb.)
Uranium 235 and uranium 238 are isotope they are chemically different why?
I LIKE PIGS IN A BLANKET I think ,because when hit Uranium-238 by a neutron, it becomes uranium-239, an unstable isotope which returns into neptunium-239, which then itself decays, with a half-life of 2.355 days, into plutonium-239. ------------------------ Differences in nucleus stability and nuclear cross sections for fission with thermal neutrons.

What way do isotopes of an element differ?
I do not know about anything beyond that, but that much I'm certain on.
I don't know about the above answer but from what I know in Chemistry is that the protons is what makes the isotopes of each element differ and the neutrons. Hope this helps
I think the first answer is correct. The protons do not make any difference. That's from AP Bio knowlege.
What changes occur when a radioactive isotope disintegrates?
When a radioactive isotope disintegrates, it releases radiation in the form of alpha or beta particles, gamma rays, or neutrons. This process changes the atom's nucleus, leading to the formation of a different element or isotope. The disintegration continues until a stable atom is reached.
What makes isotopes of the same element chemically alike?
Isotopes of the same element have the same number of protons. They will also have the same number of electrons in a neutral state. Where they differ is in the number of neutrons in the nucleus. The chemical properties of an element are almost entirely determined by its electron structure, since chemical bonds can be understood as the transfer or sharing of electrons. This means isotopes of the same element will behave in the same way chemically. They will form the same chemical compounds and be largely indistinguishable from their isotopic brethren.
Isotopes such as radioisotopes, which are 'compounds containing radioactive forms of atoms, can be introduced into the body for the purpose of imaging, evaluating organ function, or localizing disease or tumors.' Modern uses of isotopes that are useful to us are smoke detectors, irradiation in pest control, agriculture applications (radioactive tracers), medical uses, etc. mike was here Additional uses come from the process of nuclear fission. It is used in nuclear power plants and in atom bombs.
How are two isotopes of an element similar?
The nucleus contains both protons and neutrons. An element has a fixed number of protons but may exist with various numbers of neutrons. The sum of the protons and neutrons is the mass number. For example, helium exists as 3He(2 protons and one neutron) or as 4He (2 protons and 2 neutrons). The two forms of helium are called isotopes of helium. Isotopes of an element have the same chemical properties but different weights. Some elements have many isomers. Tin (Sn) has about 38 known isotopes.

What is the definition of isotopes?
isotopes are atoms of the same element, having same atomic number but different atomic masses due to the difference in the number of neutrons present
Isotopes are atoms that have differing numbers of neutrons, but the same number of protons.
