What is a Isotopic Fractionation?
Separation of a mixture according its isotopic composition.
Why does the modern periodic table not arrange argon in order of increasing atomic mass?
The inversion is due to the isotopic composition of these elements.
How you determined the relative atomic mass of oxygen?
The atomic weight (not mass) of any element is determined taking into account the isotopic composition and the atomic masses of these isotopes.
What is need to determine atomic mass of chlorine?
For the determination of the atomic weight (not mass) of chlorine we need to know the isotopic composition of Cl and the atomic masses of the isotopes.
What is the fraction in calculating the average atomic weight of an element?
The atomic weight (not mass) of a chemical element is calculated considering the isotopic composition of the element and the atomic masses (not weights) of these isotopes.
What is a Isotopic Fractionation?
Separation of a mixture according its isotopic composition.
Can water dissolve isotopes?
The solubility of a molecule is not dependent on the isotopic composition. In other words, if a molecule with a particular isotopic composition is soluble then so are all of its isotopomers and isotopologues.
What is unusual about the isotopic composition of bromine?
quecdfhlejtiem,sd,lgkdofigoikdfpvgz/.fds,pweotpwketglrkd
How do you determine when isotopes are most abundant?
Isotopic composition is determined by mass spectrometry.
Are elements a pure mixture?
Chemical elements are not mixtures (I do not think to the isotopic composition).
What is an allobar?
In physics, an allobar is any form of an element with a different isotopic composition to that of the natural element.
What has the author W Dansgaard written?
W. Dansgaard has written: 'The isotopic composition of natural waters' -- subject(s): Water, Isotopes, Composition, Ice
What equipment is used to calculate 2 types of isotopes found in rock?
Isotopic composition is determined by mass spectrometry.
Why does the modern periodic table not arrange argon in order of increasing atomic mass?
The inversion is due to the isotopic composition of these elements.
Elements in atomic bomb?
Atomic bombs contain uranium (highly enriched in the isotope 235U) or plutonium (a very specific isotopic composition).
How do you tell a meteorite from a piece of iron?
If the isotopic composition of a piece of iron, or rock, is not the one typically found on Earth, then the suspicion is strong that it originated in outer space.
What are the approximate levels of carbon isotopes found on earth?
The isotopic composition of carbon is:- carbon-12; 98,9 %- carbon-13: 1,1 %- carbon-14: traces
