1Mass spectrometry can be used to identify isotopes of elements.1 (a)(i) In terms of fundamental particles, state the difference between isotopes of an element.Different number Iamount of neutrons(1 mark)1(a)(ii) State why isotopes of an element have the same chemical properties.Same electr...
Isotopes of an element have substantially the same chemical and. physical properties and it is 13 a difficult matter to separate them. So far as there are methods of isotope separation they depend upon quite small differences; upon differences in properties more or less directly associated with th...
How Many Protons? The atomic number on the Periodic Table identifies the number of protons in any atom of that element. Copper, atomic number 29, has 29 protons. Finding the atomic number of an element reveals the number of protons.
Method for separating the isotopes of an element in particular of a metal having a high atomic weightThe invention relates to a process and apparatus for the separation of the isotopes of a body, and particularly of a heavy metal. The process comprises the preparation of a tension-active ...

aThe element X has three isotopes: X-221, X-220, and X-218, with masses 220.9, 220.0, and 218.1 amu. The relative abundances of these three isotopes are 74.22%, 12.78%, and 13.00%, respectively. Calculate the atomic mass of element X. 元素x有三同位素: X-221, X-220和X-218,与大量...
One atom of this isotope has a mass of 9.123 x 10-23 g. Identify the element and give its atomic mass. I'm not sure how to do this because we are not given any conversions between grams and moles...Question 2) A compound containing only sulfur and nitrogen is 69.6% S by mass; ...
We have seen that isotopes differ in mass number. The mass number has very little bearing on chemical reactions; therefore thereactivityand chemical reactions of an element's different isotopes are almost identical. The physical properties of atoms, however, do depend on mass. This enables isotopes...
