212 208 A
PO ---> PB + X
94 82 Z
Express you answer as an interger

Part B
What is the value of Z in the following nuclear reaction?
212 208 A
PO ---> PB + X
94 82 Z
Express you answer as an interger

Expert Solution

*Note: Are you sure you copied down the problem right? Po (Polonium) has atomic number \(84,\) not \(94 .\) Plutonium (Pu) is \(94 .\) There is only one atomic number for each unique element (i.e., 84 defines Po).

In nuclear reactions, the number of nucleons (protons and neutrons) must be the same on both sides of the equation.

Assuming this is the correct chemical reaction you are trying to express,

\({ }_{84}^{212} \mathrm{PO} \rightarrow{ }_{82}^{208} \mathrm{~PB}+{ }_{Z}^{A} \mathrm{X}\)

A represents the mass number (protons + neutrons). Hence, \(A=212-208=4\).

\(Z\) represents the atomic number. Hence, \(Z=84-82=2\)

The element with this atomic arrangement is Helium (He), which has 2 protons and 2 neutrons for a total of 4 nucleons. This is an example of alpha decay, a form of radioactive decay which releases an alpha (a) particle (He).

1. Which one describes not about a nuclear reaction but about a chemical reaction? Protons, neutrons, electrons, and other elementary particles may be involved. Rates of reaction normally are not affected by temperature, pressure, and catalysts. Only electrons in atomic or molecular orbitals are involved in the breaking and forming of bonds. Elements are converted from one to another. 2. If 12% of the original amount of a certain radioactive isotope is left after 5.2 years of its radioactive decay,...
