Chemistry -> Nuclearchemistry -> Radioactivity

Beta decay is a kind of radioactive decay in which a beta particle is emitted from the atom.

A beta particle consists of only an electron that was ejected from the atom. Therefore, the notation for a beta particle is the following:

-1 indicates that there's only the electron and 0 for atomic mass indicates there are no protons or neutrons.

With the concept of a beta particle in mind, we can write the equation aiming to keep both sides of the equation balanced. For Carbon-14 (atomic number = 6), we have the following equation:

For the equation to be balanced in terms of atomic number and atomic mass, we simply do:

Atomic number

6 + 1 = 7

Atomic mass

and 14+0 = 14

The element that has an atomic number of 7 is Nitrogen (N). So the final equation is the following:

Final answer:


_6^(14)C\rightarrow_7^(14)N+\text{ }_(-1)^0\beta
