Download Ebook Chemistry Isotope Notation Answer Key WordPress.com Isotope Notation Chem Worksheet 4-2 Nam Any given element can have more than one isotope. The notation of an isotope occurs by adding a subscipt and superscript to the left side of an element such as 238 92U (uranium isotope) 4. It is both naturally occurring and a produced by fission. The most common isotope of lithium is lithium-7 which accounts for over 92 percent of all the naturally occurring lithium on earth. Remember that the mass number is the number of protons and neutrons. Observe: Set the protons to 8 and the neutrons to 9. The origin of the name Lithium comes from the Greek wordlithose which means "stone." Based on the atomic mass, which isotope should be more abundant? 7 years ago.

Note, the mass spectrum in Figure 2.3.8 (b) gives the relative abundance of each isotope, with the peak normalized to the isotope with the highest abundance. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons. To diStinguish between the different isotopes of an atom, the element is named with its mass number, for example lithium-7. However, for both purposes it must be very pure Li-7, otherwise tritium is formed by neutron capture (see later section). All lithium atoms, regardless of the isotope, will have three protons. The mass number, however, is 6 in the isotope with 3 neutrons, and 7 in the isotope with 4 neutrons. These... Our experts can answer your tough homework and study questions.
