Question

What is the isotope notation for carbon-14?

Answer 1

`""_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!
