# What is the isotope notation for carbon-14?

May 28, 2018

""_6^14 C

#### Explanation:

Isotope notation is of the form

""_Z^A X

where $Z$ is the atomic number (number of protons), $A$ is the mass number (sum of protons and neutrons), and $X$ is the element.

In Carbon-$14$, $14$ is the mass number (sum of protons and neutrons). This is our $A$.

Carbon has the atomic symbol $C$, and it has $6$ protons. This is the atomic number, or $A$. Thus, the isotope notation for Carbon-$14$ is

""_6^14 C

Hope this helps!
