Nuclear equations and conservation of charge

In summary, the beta decay equation ^{14}_{6}C\rightarrow^{14}_{7}N+e^{-}+\overline{\nu}_{e} is commonly written without a positive charge on the nitrogen atom, even though it may seem more accurate for charge conservation. This is because the equation is referring to the nucleus, not the atom itself. The positive charge is already accounted for in the atomic number of nitrogen.

Do you know why in most textbooks, like on http://www.lbl.gov/abc/Basic.html or http://books.google.com/books?id=xD0AwBQECasC&pg=PA196 beta decay equations are written like

[itex]^{14}_{6}C\rightarrow^{14}_{7}N+e^{-}+\overline{\nu}_{e}[/itex]

instead of

[itex]^{14}_{6}C\rightarrow^{14}_{7}N^{+}+e^{-}+\overline{\nu}_{e}[/itex]

Wouldn't the latter be more correct as regards conservation of charge ?

I usually see it written as

[itex]^{14}_{6}C\rightarrow^{14}_{7}N+^{ 0}_{-1}e+^{0}_{0}\overline{\nu}_{e}[/itex]

The equation is discussing the nucleus, not the atom. So no need to put a + in front of the N.

completely agree with Vanadium... the + is included in the 7 of Nitrogen

Thanks for all the replies.
 

1. What is a nuclear equation?

A nuclear equation is a representation of a nuclear reaction, where the reactants and products are written as nuclei and are balanced in terms of mass number and atomic number.

2. How do I balance a nuclear equation?

To balance a nuclear equation, the number of protons (atomic number) and the total number of nucleons (mass number) must be equal on both sides of the equation. This can be achieved by adding appropriate subscripts and superscripts to the reactants and products.

3. What is conservation of charge in nuclear equations?

Conservation of charge in nuclear equations means that the total electric charge of the reactants and products must be equal. This is achieved by balancing the number of protons (positive charge) and electrons (negative charge) on both sides of the equation.

4. Can nuclear equations be used to predict the outcome of a nuclear reaction?

Yes, nuclear equations can be used to predict the outcome of a nuclear reaction. By balancing the equation and knowing the properties of the reactants, we can determine the properties of the products, such as their mass and charge.

5. What is a nuclear decay and how is it represented in a nuclear equation?

A nuclear decay is a type of nuclear reaction where a nucleus emits particles or energy in order to become more stable. It is represented in a nuclear equation by showing the reactant nucleus and the resulting products, along with the type of decay (alpha, beta, or gamma) and the resulting change in mass number and atomic number.
