Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.
Explain why it is impossible to separate the different isotopes of an element by ordinary chemical means?
Chemical reactions occur because of interaction between electrons, either donation or sharing. Isotopes have the same number of electrons (and protons) which is why they are considered to be the same element. The difference in isotopes is the number of neutrons - which affects the overall mass of the atom, but not its reactivity. This means that chemical means can't be used, instead you have to look for physical separation techniques.
What is the most common instrument used to measure isotope?
The most common instrument used to measure isotopes is a mass spectrometer. Mass spectrometry allows scientists to accurately determine the mass and abundance of isotopes in a sample. It works by ionizing the atoms in the sample and separating them based on their mass-to-charge ratio.
What element used in fission?
The isotopes 233U, 235U, 239Pu, 241Pu for a fission with low energy neutrons.
What is the hyphen notation for si in chemistry?
In chemistry, hyphen notation is used to indicate the isotopes of an element by following the element's symbol with a hyphen and the mass number. For silicon (Si), the common isotopes are represented as Si-28, Si-29, and Si-30, where the numbers denote the mass numbers of the isotopes. This notation helps differentiate between the isotopes based on their neutron counts.
What element was used in the first h-bomb explosion?
Hydrogen, in the form of liquid deuterium and tritium isotopes. The test shot was the 1952 Ivy Mike device.
Is the atomic mass used for the mass of an element which has isotopes?
Yes, it must be used as all elements have one or more isotopes and all elements have an atomic mass.

What is the element uranium used for in medicine?
reactors to make medical isotopes of other elements
Is coinium a good analogy or model for isotopes?
No, coinium is not a good analogy or model for isotopes. Isotopes are atoms of the same element with different numbers of neutrons, while coinium is a hypothetical element used to illustrate the concept of isotopes in a simplified manner. It is important to understand that isotopes are real atomic entities with distinct properties, not just placeholders like coinium.
Atomic mass used in a sentence?
The atomic mass of an element is the weighted average of the masses of all the stable isotopes of the element (if it has any), weighted by the natural occurrence levels of the isotopes in the elements as found on earth or in the atmosphere.
What element is used in nuclear fuel?
The question should not be, what element, but what isotope. Several easily fissible isotopes are used, such as Uranium-235. But note that the element Uranium as such is not usable - only that specific isotope.
What is a fish scaler?
A device used to separate the scales from the fish.
What do you call a glass device that can be used to separate light?
A prism.
How can a spectroscope be used to identify an element heated to incandescence?
When an element is heated to incandescence, it emits light at specific wavelengths characteristic of that element. A spectroscope can separate these wavelengths, producing a unique spectral pattern called an emission spectrum. By analyzing this spectrum, scientists can identify the element present based on the specific wavelengths of light emitted.
What element used in fission?
The isotopes 233U, 235U, 239Pu, 241Pu for a fission with low energy neutrons.
