Nuclear symbol

The composition of a nucleus is shown by its nuclear symbol. Here, the atomic number appears as a subscript at the lower left of the symbol of the element The mass number is written as a superscript at the upper left... 

The nuclear symbols for the isotopes of hydrogen and uranium referred to above are... 

Relate a nuclear symbol to the number of protons and neutrons in the nucleus. 

Selenium is widely sold as a dietary supplement. It is advertised to protect women from breast cancer. Write the nuclear symbol for naturally occurring selenium. It has 34 protons and 46 neutrons. 

How do the isotopes of Cu-63 and Cu-65 differ from each other Write nuclear symbols for both. 

Consider the following nuclear symbols. How many protons, neutrons, and electrons does each element have What elements do R T, and X represent ... 

WEB See the definition of isobars in Question 15. Consider Na-21 and write the nuclear symbol for... 

A student saw the following nuclear symbol for an unknown element iiX. Which of the following statements about X and ffX are true ... 

Copper has two naturally occurring isotopes. Cu-63 has an atomic mass of62.9296 amu and an abundance of 69.17%. What is die atonic mass of the second isotope What is its nuclear symbol ... 

The reactions that we discuss in this chapter will be represented by nuclear equations. An equation of this type uses nuclear symbols such as those written above in other respects it resembles an ordinary chemical equation. A nuclear equation must be balanced with respect to nuclear charge (atomic number) and nuclear mass (mass number). To see what that means, consider an equation that we will have a lot more to say about later in this chapter ... 

Nuclear symbol Charge Number of protons Number of neutrons Number of electrons g 60... 

Write the nuclear symbols for the following nuclides (a) the one that contains 92 protons and 143 neutrons and (b) the carbon isotope that has 8 neutrons. 

Nuclear symbolism disregards valence and electrons and always includes the mass number of the isotope (the whole number nearest the atomic weight of the isotope), the atomic number of the element, and the symbol of the element. The mass number is shown as a superscript preceding the symbol, and the atomic number is shown as a subscript preceding the symbol. This notation is illustrated by the following examples ... 

Write the complete nuclear symbols for the most common isotope (by the mass number) of sodium, of phosphorus, and of iodine. 

Nuclear Symbols and Stability, Fission, Fusion, Half-life, and Nuclear Equations... 

There are two standard methods of identifying isotopes. One method is to write the mass number with a hyphen after the name of an element. For example, the helium isotope shown on the left in Figure 14 is written helium-3, while the isotope shown on the right is written as helium-4. The second method shows the composition of a nucleus as the isotope s nuclear symbol. Using this method, the notations for the two helium isotopes shown in Figure 14 are written below. 

Write nuclear symbols for isotopes of uranium that have the following numbers of neutrons. The atomic number of uranium... 

A deuteron is the nucleus of an isotope of hydrogen, deuterium. The nuclear symbol for a deuteron (D) is jH. In a nuclear symbol of this kind, the superscript (2, in this case) represents the mass number of the particle (the total number of protons and neutrons), while the subscript (1, in this case) represents the atomic number, or the total number of protons. 

Write the complete nuclear symbols for natural sodium, phosphorus, and iodine. Each has only one stable isotope. 

We shall designate the nucleus using nuclear symbols, analogous to the atomic symbols that were introduced in Section 2.1. The nuclear symbols consist of the elemental symbol, the atomic number (the number of protons in the nucleus), and the mass number, which is defined as the sum of neutrons and protons in the nucleus.
